Hi,

We have a softphone client using H.264 codec.
When we made a call to FS, we found that the OK response of FS for the INVITE missing something.
There is a SDP media attribute like this from softphone client:

Media Attribute (a): fmtp:116 profile-level-id=42000C;packetization-mode=0

But in the OK SDP of FS, we could't find this info.
The softphone client would choose other resolution for this call.
We know that the H.264 is a pass through video codec in FS.
Our question is that is it possible and how can we add the attribute into the OK SDP?

FreeSWITCH Version 1.3.17.

Thanks.

Jimmy
