Hi, We have FreesSWITCH runing on version 11066, which INVITE with iLBC@30i number 102, however the recent version INVITE with iLBC@30i number 97. Unfortunately I have a broken sip client only talks with RTP payload 102. So here is the question: 1) What's the difference between 97 and 102? The default value changed since version 11066? 2) Is it configurable? Is it part of sofia-lib or FS? Thank you.
Once you're in dynamic range you should compare the codec name not number. /b On May 8, 2009, at 2:04 AM, seven wrote:

Should be no difference.
2) Is it configurable? Is it part of sofia-lib or FS?
Nope shouldn't matter.
Thank you.

Thank you. It must be changeable somewhere in the source code, can you help me to find out? I want it send 102 by default.
Thank you.

No thats not how the dynamic range works. You can change it in mod_ilbc.c but again NOT the right way. Your phone is broken and should be fixed. /b On May 8, 2009, at 2:50 AM, seven wrote:

actually I think we can remove the 102 version that was there for some google talk thing and I don't think we they do that anymore I'll have to test but ... if we invite to you with mod=30 you have to do 30 no exceptions as per the iLBC spec. /b On May 8, 2009, at 4:04 AM, seven wrote:

Why FS INVITE with mode=30 and 97 but not 98/102 as I'm using iLBC@30i ?

sure the client is broken. but it only do the right thing when you invite me with 102 and mod=30. Please don't remove the 102 before I had my client fixed ;) btw, client can invite with 102 to FS without problem. Thank you again. I think I can make the client work by remove the other versions. If we need multi versions in the future,, I'd like to make a patch make it configurable.
