Codec Restriction Help Please

Unanswered Question
Oct 7th, 2009

Kindly assist with this pertinent problem.

How do i filter the number of supported codecs on my sip-outbound trunk? (i would like to enable support for only the following codecs (t38,g729ab,pcmu,pcma,gsm-hr). Due to the large number of supported codecs by default on the media gateway (as5400-xm) packets get fragmented as the mtu size of 1500 is exceeded and as such calls fail because the SIP invite never gets to the other end. thanks

Thanks for your response/help p.bevilacqua.


I have checked the documentation. however can you let me know exactly which of these would solve the problem?

By Editing the Trunk Group Property

1. Traffic -> Trunk Groups -> TrunkGrp Property -> GWDefaultCodecString


OR


By Editing the Result Type for DP

2. Number Analysis -> Result -> Codec -> CodecString


thanks again
