Summary: RTP Media Port Change Ignored
Description:
In a SIP conversation, asterisk is sending an OK to a SIP Reinvite with a
media port change. Asterisk is not using this new port and will continue to
use the original port in the original invite. In the example below, when
connecting to 71.116.126.81, the original media port was 7750. A reinvite
was made to port 7752, however asterisk will continue to use 7750. This can
be reproduced and has same behavior no matter how the canreinvite flag is
set (ie no, yes, update, etc.). This can be tested by calling to
3366 at conf.zipdx.com and pressing 2. This test was done to
3366 at conf.hificonf.com, which is a lab server active at the time of this
post.
