Tunisia: SIP providers and connecting a number to your PBX

We do not issue phone numbers: the venue buys a Tunisian number from a carrier or a local VoIP provider and connects it to its own PBX as a trunk. Everything that is the same in every country — trunk modes, form fields, network requirements and connectivity checks — is covered in the overview “Connecting a provider's number to your PBX”. This page covers only the Tunisian part: where to get a number, what to enter in the admin panel and what people trip over in this country.

The data was collected on 9 September 2026 from the websites of carriers and resellers, acts of the regulator INT and the Telecommunications Code; links are in the “Sources” section. A dedicated PBX is created for venues in Tunisia: the regulator does not require the venue itself to hold a licence.

In brief#

• You can buy a trunk for your own PBX in Tunisia, but the licence is required from the seller, not from the venue. Under the Telecommunications Code, a public network is built under a licence, and telecom services are provided under the minister's prior authorisation (articles 5 and 6). The venue here is a subscriber; your only job is to buy the number from someone who holds that authorisation.
• No Tunisian carrier publishes trunk parameters. The host, port, transport, authorisation mode and codecs are named by the engineer at provisioning time. That does not mean “there is no trunk” — it means you must ask three questions before signing and get the answers in writing.
• There are three candidates. Orange Tunisie — “Téléphonie Fixe Business”, built on VoIP with an SBC in the carrier's own data centre; Tunisie Telecom — “solutions Trunk SIP” plus the Cloud PBX hosted service; DIGIVOIP TUNISIA — the only local company that publicly sells a SIP trunk to a third-party PBX and names Asterisk, FreeSWITCH and 3CX outright.
• The main technical risk in this country is an encrypted interconnect. DIGIVOIP's connection diagram shows SIP/TLS with SRTP, and Orange interconnects through an SBC with Microsoft Teams compatibility — which for carriers of that class usually means TLS as well. Our PBX does not support TLS or SRTP for trunks, so the first question to any seller is “will you hand over the trunk over UDP or TCP on 5060 with G.711 a-law?”, not “how many channels”.
• The second risk is delivery that does not run over the internet. Tunisie Telecom describes its trunk as a “réseau mutualisé”, and both Ooredoo and Orange have product lines where the switch sits inside the venue. Our PBX lives in the cloud and accepts a trunk only over the public internet, to its static IP address.
• Numbers are eight digits long, while a line is matched on seven. A Tunisian national number is exactly 8 digits, and the last seven of them are used for matching — the first digit is dropped. The landline 71 234 567 and the mobile 21 234 567 share the tail 1234567 and will collapse into a single line.
• A +216 number is almost impossible to buy from abroad. DIDWW states plainly that “Local SIP Trunking — Not available” for Tunisia, didlogic offers a national number without an area code, and Freezvon charges $150 a month for the national one.

Numbers in Tunisia#

The country code is +216. There is no national trunk prefix: inside the country you dial exactly 8 digits, and the international prefix is 00. The 8-digit length is mandatory for everything except numbers beginning with “1” and “87” (arrêté of 02/12/2009 approving the national numbering plan, article 4). The first digit sets the type of service (article 5): 2, 3, 4, 5, 7, 9 — telephony, 8 — intelligent networks, 1 — utility and emergency services, 6 — reserved.

• Area codes are assigned by INT decisions rather than by the plan itself. According to open sources as of 09/09/2026: Greater Tunis — 70, 71, 79; Bizerte, Nabeul, Zaghouan — 72; Sousse, Monastir, Mahdia — 73; Sfax — 74; Gabès, Medenine, Tataouine, Kebili — 75; Gafsa, Tozeur, Sidi Bouzid — 76; Kairouan, Kasserine — 77; Béja, Jendouba, Kef, Siliana — 78. Mobile ranges: 9X — Tunisie Telecom, 2X — Ooredoo, 5X — Orange, 4X — the virtual operator Elissa. We could not confirm this from an official act — check which carrier holds your number when you order it.
• No Tunisian carrier has published the form in which the number arrives in an inbound call. Be ready for three variants: E.164 without the plus sign (21671234567), the national 8 digits (71234567), or the trunk login instead of a number. On the first connection look at the SIP trace to see what the provider sends, and only then create your lines.
• Carriers do not publish codecs. The only list published in the country is DIGIVOIP's: G.711a, G.711u, G.722, G.729, Opus, T.38. We support G.711 a-law, G.711 µ-law and G.722; ask for them explicitly.
• Emergency numbers (same arrêté, article 6): 190 — SAMU, 193 — national guard, 194 — maritime guard, 197 — police, 198 — civil protection. Emergency calls are not carried by our PBX — an ordinary phone or a mobile must stay available on every shift.

Who sells a number with a SIP trunk#

Below are cards for the three sellers worth approaching for a trunk, plus a review of the rest. All of them issue parameters under contract; the full list of questions for the account manager is in “What to ask your provider”.

Orange Tunisie — Téléphonie Fixe Business#

The country's second fixed-line carrier. Its business catalogue holds two voice products, and telling them apart matters. Téléphonie Fixe Business is described outright as a “solution de communication simple et fiable, basée sur la technologie VoIP”, “compatible avec les standards téléphoniques”: pay-as-you-go billing or bundles, plus “cloud integration with an SBC hosted in Orange's data centres, with Microsoft Teams compatibility”. Capacity is measured in simultaneous calls: Livebox Business — under 30 AS (appels simultanés), “compatible with your equipment”; Corporate Voice — above 30 AS. Téléphonie Managée is the second line, where Orange supplies, installs and configures the equipment itself; it is not usable with our PBX.

Orange Tunisie publishes no technical trunk parameters: there are no prices and no SLA on the site, and the only way in is the “Je suis intéressé” form.

What to enter in the admin panel (Telephony → “Trunks and connections” → “Add provider”):

What to set up on the provider's side: order Corporate Voice, not Livebox and not Téléphonie Managée → state the design up front — “PBX in the cloud, our own static IP, trunk delivered over the public internet” → give the engineer the address from the “Server” tab → insist on UDP or TCP with G.711 a-law or G.722 → point the numbers at the trunk → confirm the number format in inbound calls.

Pitfalls ⚠️

• The SBC and Teams compatibility are a reason to ask about TLS first. If the interconnect is TLS with SRTP only, the connection will not work.
• Livebox Business is a box on your premises. “Compatible with your equipment” in its description means desk phones and a small on-site PBX, not a switch in the cloud.
• There are no prices or parameters on the site at all. Everything you get before a manager calls is a contact form, so allow time for correspondence.

Tunisie Telecom — Trunk SIP and Cloud PBX#

The state incumbent, holder of most of the geographic numbering. Its “Fixe” business line-up consists of Cloud PBX (the carrier's hosted PBX: IVR, call forwarding, conferences — 9.9 DT excluding tax per user per month, 0.035 DT including tax per domestic minute, free activation), PACK PRO (a turnkey on-site IPBX, platforms from 20 to 3,000 users, equipment and installation by the carrier), ProFix (hour bundles: 12 hours for 21 DT excluding tax, 0.039 DT per minute beyond the bundle) and Forfaits partagés (hour bundles shared across lines: from 50 hours for 315 DT to 1,500 hours for 7,875 DT excluding tax, a 12-month minimum term).

The trunk itself has no dedicated page on the site. The phrase “solutions Trunk SIP de Tunisie Télécom, permettant à l'entreprise de bénéficier d'un réseau mutualisé supportant les flux de trafic multiservices données et voix” comes from an interview with the head of the enterprise market: the product exists, but it is ordered through the Direction Marché Entreprises. Cloud PBX is the carrier's own switch, not a trunk to ours — buying it instead of a trunk makes no sense.

What to enter in the admin panel:

What to set up on the provider's side: state that the PBX is yours and lives in the cloud → require the trunk over the public internet to our static IP, not over the carrier's managed network → codecs G.711 a-law or G.722 → point the purchased numbers at the trunk → allow the media stream towards us.

Pitfalls ⚠️

• “Réseau mutualisé” most likely means delivery over the carrier's own network (MPLS or a VPN to your premises) rather than over the internet. That is exactly the case our cloud PBX cannot handle, so clarify it before signing.
• The site tunisietelecom.tn does not open from Europe at all. The prices and bundle contents above were taken from web archive snapshots of 2024–2025 — verify them with the account manager, they may have changed.
• PACK PRO is an on-site switch, the same dead end as Orange's Téléphonie Managée.

DIGIVOIP — a trunk to a third-party PBX#

DIGIVOIP TUNISIA SARL (Centre Urbain Nord, Tunis) runs on an open-source stack and is the only local supplier that publicly sells a SIP trunk to a third-party switch rather than just its own hosted PBX. Its service description reads: “SIP Trunking Premium… connect your IPBX to the whole world”, over 600 direct routes to more than 100 countries, and in the FAQ outright — “our SIP Trunking is compatible with every IPBX on the market: Asterisk, FreeSWITCH, 3CX, Avaya, Cisco”, the number of simultaneous channels “has no technical limit”, provisioning takes “less than 7 business days”, express 48 hours. Prices for the hosted PBX are published (Tiny — 100 TND a month for 5 extensions and 2 trunks, Small — 170 TND, Medium — 296 TND), and so are the codecs: G.711a, G.711u, G.722, G.729, Opus, T.38.

⚠️ The published connection design does not suit us as drawn: “your IPBX → SIP/TLS → DIGIVOIP”, media “RTP/SRTP”, and “TLS/SRTP encryption” in the security section. We have no TLS trunks at all. The G.711 and G.722 codecs we need are on their list, though — so the whole question comes down to transport, and it has to be asked before you pay.

What to enter in the admin panel:

What to set up on the provider's side: require the trunk over UDP or TCP on 5060 with G.711 a-law or µ-law instead of TLS/SRTP → hand over your PBX's static IP from the “Server” tab → open the destinations you need for outbound calls → point the purchased number at the trunk.

Pitfalls ⚠️

• They most likely have no Tunisian number. DIDs are advertised “in 100+ countries”, but +216 is not named among them, and the company holds no visible public authorisation from the regulator. You will have to source the number separately — from a carrier or an international aggregator.
• Opus on the codec list does not help: we do not support it, so agree on G.711 specifically.
• Contacts: +216 70 13 72 00, sales@digivoip.tn, support around the clock, sales on weekdays.

Ooredoo Tunisie — no trunk on the shelf#

The country's largest carrier by subscriber base. Its “Voix Fixe” business section holds three items — Office in a Box, Business Centress and Business Voice — but only the first is publicly described, and it does not suit us: “high-speed internet (ADSL and FTTx) + an IPBX embedded in the Box Pro + voice with up to 6 handsets (DECT or IP) + up to 12 simultaneous calls (2 per handset) + an IPSec VPN + fixed IP addresses”. That is a switch inside the carrier's own equipment: there is no trunk going out of it.

The Business Centress (Centrex) and Business Voice pages return “Oops! that link is broken”, and their contents are only visible in the catalogue menu. There is no way to verify publicly what is sold there.

What to ask the business department: is Business Voice delivered as a SIP trunk to a third-party public static IP over the internet (rather than only to the Box Pro), over which transport, in which authorisation mode and with which codecs. The full list is in “What to ask your provider”. If the answer is “only to our Box” or “only over our access line”, the connection will not work.

Internet providers and anonymous storefronts#

International providers with Tunisian numbers#

Tunisia is not a country where a landline number is bought online in an hour. What is confirmed by provider documents as of 09/09/2026:

• DIDWW — on its Tunisia page the local tier is marked plainly “Local SIP Trunking: Not available”, and only international A-Z termination is offered. It has no Tunisian numbers.
• didlogic — in its table of Tunisian number types only the national +216 and the toll-free 800 rows are filled in; no local or mobile codes are listed. Most numbers are activated within 8 hours, or up to 48 hours when local documents are required.
• Freezvon — national +216: $20 setup, $150 a month, forwarding to SIP at $0.45 a minute; the “Sousse” option costs $20, $210 a month and $0.99 a minute.
• CommPeak — advertises local, non-geographic and toll-free numbers for Tunisia.
• Telnyx — a Tunisian numbers page exists, but actual availability is only visible in the portal. Ask for written confirmation before paying.
• Twilio, Zadarma, Plivo — none of them has a dedicated Tunisian numbers page; Zadarma only lists rates for calls to Tunisia.

⚠️ “+216 virtual number” storefronts get the details wrong. The sample numbers at CommPeak (+216 65…, +216 36…) and Freezvon's “31” code do not match the numbering plan: range “6” is reserved and 3X is not handed out geographically like that. Such storefronts cannot be treated as proof that a number exists — verify it with a real order. KYC: Tunisia is one of the countries where a number usually requires proof of a legal entity and an address; no aggregator publishes the exact document list.

Trunk parameters at international providers are standard and described in the admin catalogue cards: most use REGISTER with a login and password from the portal, some use IP authorisation.

Number porting#

• Number portability works in Tunisia — INT decision no. 58/2012 of 5 July 2012, commercially launched on 16 July 2013. It is mandatory for every public network operator.
• What can be ported (article 3.1): geographic fixed numbers, including direct dial-in (DDI) numbers, the non-geographic ranges 80 (libre appel) and 82 (coûts partagés), and mobile numbers.
• Who files the request — the subscriber, in writing and against a receipt, with the receiving operator. The request simultaneously terminates the contract with the previous operator for those numbers.
• Deadlines (article 5.3): the subscriber has 1 day to withdraw the request, the donor operator answers within 3 business days, and 2 business days are allowed for execution; porting must complete no later than 6 days from the request date.
• Limits. A landline number can be ported only inside its own geographic area and only to another fixed-line operator; a mobile number only to a mobile operator. The previous operator's services are not carried over.
• Register the number to the company from the start. A number bought in an individual's name is lost when the venue changes owner; a number registered to an intermediary has to be ported through that intermediary.
• ⚠️ Changing the PBX's public address breaks a trunk that uses IP authorisation. If the dedicated machine is recreated, tell the carrier the new address in advance.

Rules and paperwork#

If it does not work#

1. The provider only offers the trunk over TLS with SRTP. This is the most likely local cause, and no setting fixes it: our trunks speak UDP and TCP only. Demand the ordinary port 5060 with G.711 a-law before paying, exactly as phrased in the cards above.
2. The trunk is not delivered over the internet. “Réseau mutualisé”, MPLS, a VPN to the premises, “only over our access line” — all of these mean the call will never reach our cloud PBX. State the design — “PBX in the cloud, static IP, public internet” — in the very first conversation.
3. They sold you a hosted PBX or a box instead of a trunk. Cloud PBX and PACK PRO at Tunisie Telecom, Téléphonie Managée at Orange, Office in a Box at Ooredoo — these are somebody else's switch, not a trunk going out. The tell during the sales call: they offer you their handsets and their IPBX.
4. Two numbers collapsed into one line. A line is matched on the last seven digits, while a Tunisian number is eight digits long — the first one never takes part. A landline 7X… and a mobile 2X…/9X… with the same tail become a single line: pick numbers with different tails or separate them through routing.
5. Registration is green but no calls arrive. Check that the number is pointed at your trunk on the provider's side and that the line's “accepts calls” switch is on; then look at the SIP trace to see the form the number arrives in — the carrier may send 8 digits, E.164, or the trunk login.
6. They offered G.729 only. Our PBX speaks G.711 and G.722; with G.729 there will be no audio. DIGIVOIP has the codecs we need — ask them to switch; with carriers, settle it before signing.

The general table of symptoms and causes is in the overview, section “If calls do not come through”.

Frequently asked questions#

Can a Tunisian number be connected to my own PBX at all?#

Yes. The regulator's authorisation is required from whoever sells the service, not from the venue that uses it. You buy the number and the trunk from a carrier or a local VoIP provider that holds an authorisation, and terminate them on your own PBX. It is worth checking: providing telecom services without authorisation carries up to five years of imprisonment and a fine of up to 20,000 DT under the Telecommunications Code.

Which carrier has the better odds?#

Start with Orange Tunisie (ask for Corporate Voice, not Livebox) and Tunisie Telecom: both have a trunk as an actual product. In parallel, write to DIGIVOIP — the only local company that explicitly claims Asterisk compatibility. Three answers decide it: a trunk over the public internet to our IP, UDP or TCP instead of TLS, and the G.711 codec.

Why not simply buy from DIGIVOIP and be done with it?#

Because their connection diagram shows SIP/TLS with SRTP, and we have no TLS trunks; and because, judging by the service description, they have no Tunisian +216 number — the DIDs they advertise are in other countries. So you may well get a trunk from them, but the number will still have to come from a carrier.

Can I buy a +216 number online from abroad?#

Almost never. DIDWW provides no local trunking for Tunisia at all, didlogic offers a national number without an area code, and Freezvon charges $150 a month for the national one. A landline number for a specific Tunisian city is effectively unobtainable from abroad — confirm availability in writing before paying.

How long does connection take?#

DIGIVOIP: up to 7 business days, or 48 hours on the express track. A carrier: weeks — a contract through the business division, agreement on the technical design, installation; neither of them publishes an SLA.

Do I have to warn guests that the call is recorded?#

Yes. Organic law 2004-63 on personal data protection applies under INPDP supervision: processing requires a lawful basis or consent, so a spoken notice at the start of the call is mandatory. The PBX picks the language of that notice from the venue's country — for Tunisia that is Arabic or French.
