Hello,
I have a new ISR4431 for voice.
I have configured an ephone/ephone-dn on it.
On another site, I have an already working CCME 2911
I try to make a call from one end to the other.
On 2911 :
dial-peer voice 4001 voip
destination-pattern 265
session protocol sipv2
session target ipv4:x.x.x.x(ISR4431)
dtmf-relay rtp-nte
no vad
!
On 4431, no dial-peer
=> With this config, I can call from 2911 to 4431
But (normal), not from 4431 to 2911 ...
So I add this dial-peer on 4431
dial-peer voice 4002 voip
destination-pattern 504
session protocol sipv2
session target ipv4:x.x.x.x (2911)
dtmf-relay rtp-nte
no vad
!
Now, I can call from 4431 to 2911.
But a call from 2911 to 4431 is now failed ...
I tried to add this dial-peer to 4431 (I think I must do that on my old config to work and accept call)
dial-peer voice 5012 voip
description Appels VOIP vers 2xx (Tournai)
incoming called-number 265
But that don't help me
What can I do ?
Thx

Call fails with cause code 65 which is media negotiation failure. In the invite we see only g711ulaw being advertised. Are you limiting the calls to use only this codec anywhere in the configuration ?
07-18-2017 07:52 AM
No,
I don't find any reference to this codec ont eh 2 configurations ...

can you provide debug voip ccapi inout for this call. Also check in the cme sip/sccp phone configuration whether you are locking any specific codec at phone level or globally.
