Hey guys,

For a work research project we needed a flutter client to connect and use a 3cx server.
3cx unfortunately doesn't allow for a websocket connection.

I've succefully implemented a TCP connection with this package by abstracting a SocketInterface class that two WebSocket, and TcpSocket classes extend. Can register with the 3CX server, make calls, talk successfully and hang up.

I'm reaching out to field the interest in this as a future pull request!

Cheers

@mikaelwills how you do that please ?

Its all in the example app now, call the SIPUAHelper's start() function wih TransportType.TCP in your settings transport type.

SIP/2.0 488 Not acceptable here

What PBX server are you using? If its 3cx make sure you un-tick 'block remote non-tunnel connections' in each user.

But overall there could be many reasons why the server has said this, might not like the encryption used, if you're trying to use DTLS SRTP inside the SDP or not, or if the codecs used in the SDP aren't supported by the server.

-Server Domain (default server): [sip.wasel.sa]
-SIP Signaling Port: 5060 (TCP) .
-Protocol: We use TCP for SIP signaling.
Supported Codecs:
- We support G.711 (a-law and u-law) and G.729.
- Preferred Codec Order: G.711 > G.729 .
this is the server informations how I can change the codecs for this in the sip_ua code my account make the register but when I make the call show me that error can you help me please ?
