[Freeswitch-users] Choice of codecs for incoming call

[Александр Мустафин]

Hello, Steven.

Thank you for reply.

Maybe my DID-provider is buggy, but I've succesfull calls in the other
pbx with the same number.
Short examples below - second example is work.

         FS (1st test)

----> INVITE (PCMU,PCMA)
<---- 100 Trying
<---- 200 OK (PCMU)
----> ACK
----> Re-INVITE (PCMA)
<---- 100 Trying
<---- 488 Not Acceptable Here

         CG (2nd test)

----> INVITE (PCMU,PCMA)
<---- 100 Trying
<---- 200 OK (PCMU, PCMA)
----> ACK
----> Re-INVITE (PCMA)
<---- 100 Trying
<---- 200 OK (PCMA)
----> ACK
