Hi All,
I would like to know whether the content (SIP Methods supported) of Allow
header can change within a dialog.
For example, can 100 Trying message have "Allow: INVITE ACK BYE CANCEL
OPTIONS UPDATE" and
180 Ringing message have "Allow: INVITE ACK BYE
CANCEL OPTIONS" in the same dialog?
I don't see any specific mention of this in RFC 3261. Logically, I feel
the behavior of UA sending the above messages is not correct.
Thanks,
Jagan
