> Scenario
> INVITE arrives to asterisk, asterisk responds Busy()
> If the INVITE is retransmitted, asterisk will generate a 503 in addition to the 486.
> Attached is a patch to prevent asterisk from sending the 503 (the 486 is already being reliably transmitted)  as well as an asterisk testsuite test to validate the fix
