Problem with preferred codec and pre-ietf...

Hi,

We have been seeing the pre-ietf codec showing up in our gateway's call history even though we have specified preference to not use it. The GW IOS version is 12.2(17a).

We have set the codec preference as follows:

voice class codec 1

codec preference 1 g711ulaw

codec preference 2 g729r8

!

Anyone know why we are still seeing the pre-ietf codec in use? See call history entry below...

Thanks!

Re: Problem with preferred codec and pre-ietf...

Hi Timothy,

There is a new bug opened for this issue, which is being reviewed internally by Cisco now. Here are the bug details.

CSCed37567 - show call history brief shows calls using g729r8 pre-ietf

"show call history voice brief" shows calls using g729r8 pre-ietf codec which is supposed to

be replaced by ietf g729r8 after IOS 12.0.5T. Customer is running 12.2.17a.

Customer has not enable pre-ietf on his dial-peers.

From call log:-

IP 13.190.255.6:18648 rtt:0ms pl:0/0ms lost:0/0/0 delay:0/0/0ms g729r8 pre-ietf

This is also creating some confusion to customers.

Hope this helps!
