Dropping Voice Calls

Unanswered Question
Oct 19th, 2007

Dear all,


We have voIP between two sites, connected over MPLS and voice calls drop now and then. We use Avaya for Voice boxes and Cisco routers/switches elsewhere. QoS is configured on both ends of the MPLS to prioritize voice packets and I do not see any drops in the voice packets at both the ends under "sh policy-map interface" command.


I am new to Voice and wondering where to start the troubleshooting.


Any help is appreciated.


Thank you,

Mohan

Paste you Sh run and Sh ver, could you update when the call is dropped [after pickup the call, the call get dropped or in conversation the call get dropped].


If your call get dropped after pickup, it is due to codec mismatch.

Are you providing QoS just for the voice bearer traffic or do you also provide special handling for voice control traffic?
