Assume the following callflow.
1)INVITE/OK/ACK happens between UserA and User B for codec as PCMU.
2)User A sends a re-INVITE with the codec supported as LPC. User B
sends a 200OK with support for LPC. Meanwhile User A's codec support was
changed to GSM.
3) User A finds that it no more supports the negotiated media.
What does the User A do with this?
Should the User A respond with ACK to the 200OK and send a re-invite for
the new media (OR)
Should User A drop the 200OK responses as it no more supports the codec
and User B might be sending
media on that port after it receives an ACK from User A.
