[jitsi-users] Codec G722


#1

Hi,

in an old post i read about deactivating G722 Codec for compatibility
with some SIP servers like fritz!box, and it helped.

Is it really still necessary to deactivate it ?

I can't think of a reason why. What might be necessary is to turn off *some* (as in any) codecs as well as encryption, in situations where your server only supports UDP access and your firewall (or that of the server) does not support IP fragmentation. The point being to limit the size of your packets so that they don't get fragmented.

I just tried it out again and G722 sounds like an old venyl lp from 1940
, which is played too slow :slight_smile:

In other words, it's not compatible with (this) Fritz!Box SIP Server.
All other codes seem to work perfect.

Have no idea why ... but given all the implementations we have tested it with (e.g., Cisco, FreeSWITCH, Asterix, ZipDX, Chrome), I am willing to blame FritzBox

Is G722 used for something else rather than SIP ?

I am not sure I understand the question. Do you mean within Jitsi? If so, then yes, Jingle also uses it.

If your question was about its use in general, G.722 is supported by Chrome so any WebRTC application could end up using it.
