Hi,
we are using Freesentral with Yate 4.3. It works by default with UDP. It works fine but when we try to add cisco phone with sip preconfigured - it is not possible. If we connect to UDP the phone state is "registering" and in Yate dump error is Unauthorized!. When we add TCP listener the phone connects and works but only for outgoing calls. Incomming call come to UDP and probably it is not supported by the phone. So - we have two choises :
1. to register the Cisco phone with UDP
2. to repair TCP communications.
Both are not working as described above.
We try with manu firmwares 8.x, 9.x etc.
Can anybody help us to connect that phone and use it as expected?
I can provide logs and dumps if necessary.
Best regards,
Todor
