Carrier settings
Esta página aún no está disponible en tu idioma.
Settings for the carriers our customers connect most often, taken from trunks that work in production. For the steps to add a trunk, see Your own carrier. For an office phone system (Panasonic, Grandstream, Yeastar, 3CX, FreePBX, Issabel, Alcatel, Avaya), see Connect your PBX.
In Telephony → Add Trunk, pick the carrier: the app fills in the host, port and transport below. You add the username, password and numbers.
Yuboto
Section titled “Yuboto”MyVoIP SIP trunk
| Field | Value |
|---|---|
| Host | sip.yuboto-telephony.gr |
| Port / transport | 5060, UDP |
| Registration | on, expiry 300 |
| Username / password | from MyVoIP → Devices |
Some accounts get their own endpoint instead of the shared host. MyVoIP → Devices shows it.
Yuboto cloud PBX (vPBX) extension
When the agent should be an extension of a Yuboto cloud PBX, connect it as an extension of that PBX:
| Field | Value |
|---|---|
| Host | your PBX’s address, <name>.vpbx2.yuboto.com |
| Port / transport | the ones your PBX shows for that extension. Each PBX has its own port (5060 to 5086 in the PBXs we see), mostly over TCP |
| Username / password | the extension’s |
A wrong port or transport gets no reply at all, not an error: copy both exactly from the PBX.
Modulus
Section titled “Modulus”| Field | Value |
|---|---|
| Host | voips.modulus.gr |
| Port / transport | 5060, UDP |
| Registration | on, expiry 300 |
| Username | the Auth ID Modulus gives you, not the SIP username |
- Add every number to the trunk. Modulus sends the calls of all its customers from the same address, so we route each call by the number dialled. A call to a number that is not on any trunk is rejected rather than risk reaching another company.
Supervoice
Section titled “Supervoice”| Field | Value |
|---|---|
| Host | sip.supervoice.eu |
| Port / transport | 5061, TLS |
| Registration | on, expiry 300 |
If Supervoice gives you an outbound proxy, add it under Advanced on the trunk.
Inter Telecom
Section titled “Inter Telecom”| Field | Value |
|---|---|
| Host | sip.intertelecom.gr, or the address Inter Telecom gives you for your account |
| Port / transport | 5060, UDP |
| Registration | on, expiry 300 |
Confirm the exact host with Inter Telecom (+30 2170007000); some accounts get their own.
Telnyx
Section titled “Telnyx”| Field | Value |
|---|---|
| Host | sip.telnyx.com (sip.telnyx.eu for the EU region) |
| Port / transport | 5060, UDP |
| Registration | on |
| Username | the SIP Connection’s Auth ID |
Telnyx keeps one registration per credentials-based SIP Connection. If the same credentials are also on a softphone, desk phone or another platform, the trunk keeps dropping with 401. Details in Your own carrier → Telnyx.
Twilio
Section titled “Twilio”| Field | Value |
|---|---|
| Host | your Elastic SIP Trunk’s Termination SIP URI (<name>.pstn.twilio.com) |
| Port / transport | 5060, UDP |
| Authentication | by IP, both directions. No registration |
In Twilio, add the Voice Logica IP addresses to the trunk’s IP Access Control List (Support gives you the current list), and point its Origination at your company’s SIP address (Telephony → Call settings).
| Field | Value |
|---|---|
| Host | phone.plivo.com |
| Port / transport | 5060, UDP |
| Incoming calls | by IP: add Plivo’s inbound IPs for your region under Advanced → Authentication |
Cosmote, Vodafone and Nova
Section titled “Cosmote, Vodafone and Nova”- Business SIP trunk: Cosmote and Vodafone authenticate by IP. Ask your account manager for their signalling IPs and add them under Advanced → Authentication.
- A landline on the internet router: see Cosmote, Vodafone and Nova. Vodafone needs host
62.38.86.150, expiry 3600 (300 is rejected) and the edge device, because it accepts registrations only from inside its network.
Troubleshooting
Section titled “Troubleshooting”The SIP logs show no reply from the carrier
Wrong host, port or transport (Yuboto vPBX: check both), or the carrier accepts registrations only from inside its network (Cosmote, Vodafone): use the edge device.
The carrier answers 401 or 403
401 again and again from the start: wrong username or password. For Modulus and Telnyx the username is the Auth ID. If it registered earlier and now gets 401, the same account is also registered somewhere else: see Registration works, then keeps getting rejected.
Modulus: some calls never reach the agent
The dialled number is not on the trunk. Add it under the trunk’s numbers. Calls from Modulus are matched by number, so a missing number is rejected.
I got a 'Registration paused' email
The carrier rejected the registration several times, so we paused and keep retrying on our own (5 minutes, then longer), to keep the carrier from blocking the account. The email shows the likely cause. A successful registration recovers the trunk without any action from you.
