A SIP media flow deny-listener was to have been deleted but an unrelated listener was deleted instead due to an incorrect address/port match. For example, when the wrongly deleted listener is later meant to be deleted, there might be a SIGFPE with assertion failure "Assertion "bound listener" failed.".
Later when the wrongly deleted listener is referenced, the TMM crashes.
A SIP MRF media flow existed and was deleted. An unrelated flow exists with an address/port with wildcards such that it includes that of the media flow.
None
When a SIP media flow deny-listener is searched for deletion, an exact match is required that uniquely identifies the deny-listener, so that an unrelated listener is not deleted.
