Hello everyone,

For multiple codecs we can have an SDP like this:
m=audio 10000 RTP/AVP 0 8      ----- 0 means g711u-law and 8 means g711a-law
a=ptime:20
But this is only correct if the packet times match for
u-law and a-law.


What if you have a system where, for some reason, the
codecs have different packet times?

Can you do this?
m=audio 10000 RTP/AVP 0 -             ---- g711-ulaw
a=ptime:20
m=audio 10000 RTP/AVP 8               ---- g711 a-law
a=ptime:30

Regards,

Attila
