  1. 3cx Web Client (WebRTC) forcing OPUS on outgoing calls [twilio trunk]

    Hey there, I've been going through everything here and seen a few posts around this idea but many of them had not quite correctly identified the issue. Here is what is happening. I use twilio as my outgoing trunk, therefore I want all traffic to be using PCMU/PCMA as that's all the support. This...

    Twilio Elastic SIP Trunk Setup

    I finally figured out how to get a SIP registered trunk up and running while also handling multiple DID inbound! Which the 3cx documentation doesn't go over when using Twilio. This may seem obvious to some but to me, who doesn't mess with the technical side of phone systems too often was a huge...

  3. DTMF system not working

    Hi! We've set up 3CX with a Twilio integration. Inbound calls are working so far, except for the part where we need to use DTMF to transfer calls to extensions. So, we set up a digital receptionist that asks for an extension number, but it's not answering to the DTMF tones input. Funny enough...

  4. 3cx and Twilio Secure SIP Trunk

    Hello I've enabled SRTP for the SIP Trunk in 3cx and secure trunking in Twilio. Calls can be made and received but only last 32 seconds. Non Secure SIP call work without problem. Can I just confirm that Twilio Secure SIP will work with 3cx, or because TLS is not support they will not work as...

  5. No audio

    We are continuously getting no audio with Fanvil X4G phones (Firmware versions: 2.4.0.5572 & 2.10.0.6646) using 3 SIP trunks with Twilio, users are also unable to hear on the soft client on their mobile devices - A quick fix tends to be a restart of the server (Server is on: 15.5.15502.6).

  8. Twilio Elastic SIP Trunking with 3CX - One-Way Audio & No Outbound Calls

    I cannot get Twilio Elastic SIP Trunking to work as a SIP provider for my 3CX install (v15, linux). I have 3CX setup and working with Flowroute and it has been working fine for over a year. We want to move our SIP trunking to Twilio Elastic SIP Trunking, because of the price and the extensive...

  9. Does 3CX V15 works with Twilio?

    Hi guys. Totally new to 3CX, my apologies for any crazy question. Im trying to set up 3CX trial with a Twilio Trunk (the Trunk is also a trial, but supposed to be functional) Does 3CX V15 works with Twilio?

  10. No inbound calls using V15 with Twilio Trunk

    Setting up a new system and extension to extension works fine. Outbound calls work but inbound calls fail. Firewall test passed. Using wireshark, I can see the SIP "invite" from Twilio but 3CX responds with Status-Line: SIP/2.0 407 Proxy Authentication Required. I have read the 3CX - Twilio...
