[Linphone-developers] SDP payload negotiation

[Vadim Lebedev]

Simon,

It seems that linphone expects that for a given rtp session  a payload 
number for the outgoing and incoming streams
is same for each codec.

I see pretty often situation where   mapping of dynamic payloads  
numbers to codecs is  different for each side of connection.

Basically the offerer send an SDP saying what payloads it expected to 
receive and ANSWERE has a choice
1) adapt it's own mapping to the OFFERER
2) keep it's own mapping intact and simply reject  codecs it does not like

In any case the outgoing RTP stream should use payload numbers expected 
by  the other side


Any plans to implement this?

Or i'm missing something at it already works?


Thanks
Vadim
