Summary: Wrong branch on CANCEL after SIP INFO in early
dialog
Description:
Scenario :
A Calls Asterisk IVR
IVR answers
A enters B's ext
A pushes a DTMF while B is ringing
A hangs up
in SIP :
A INVITES Asterisk
Asterisk 200OK (IVR)
Asterisk INVITES B
B sends 180 Ringing
A sends SIP INFO
Asterisk sends SIP INFO to B
A BYEs Asterisk
Asterisk sends CANCEL with wrong branch
The UA cannot match the INVITE to the CANCEL because the CANCEL does not
have the same branch (via header) that the INVITE had.
B only ack the CANCEL without sending the required 487 to cancel the
INVITE. B Stays ringing forever. (Granted, answering a 481 to the CANCEL
might be the thing to do, but it's only a SHOULD in the RFC)
Attached is the SIP debug + core and verbose 5 (asterisk -Tvvvvvdddddngc |
tee /tmp/verbosedebug.txt) and an ethereal capture for easier reading.
