Hi,
If the codec change requested in a Re-INVITE needs to be rejected by UAS,
is it mandatory to send a 488 response to the Re-INVITE and continue
operating with the codec negotiated in the INVITE?
From section 14 of RFC 3261, looks like it's not mandatory to send a 488
response and more a implementation specific problem. In that case, is it ok
to send a 2xx response to the Re-INVITE with the codec negotiated in the
initial INVITE?
Or is this case addressed in any other standard?
Thanks,
Jagan
