Summary:                    [patch] (Call Completion / SIP) INVITE Fails
(Receive a 404 From Asterisk Server) When Using The URI Provided From A
NOTIFY(cc-r
Description: 
The ‘To’ line in our INVITE contains:

To:
<sip:10f2a43020db0a2c787fa67c6c4d279b at 192.168.233.250:5060;transport=udp>

The function in ‘find_by_notify_uri_helper’ in file chan_sip.c does a
straight strcmp of the ‘To’ with the URI it sent in the NOTIFY
(cc-ready).

This match then fails because we have added ';transport=udp'

return !strcmp(agent_pvt->notify_uri, uri) ? CMP_MATCH | CMP_STOP : 0;

agent_pvt->notify_uri =
sip:10f2a43020db0a2c787fa67c6c4d279b at 192.168.233.250:5060

uri =
sip:10f2a43020db0a2c787fa67c6c4d279b at 192.168.233.250:5060;transport=udp

The Asterisk server is NOT extracting the URI correctly from the ‘To’
line in the INVITE. So strcmp will always fail.
