Review request for Asterisk Developers.


Bugs: ASTERISK-24335
    https://issues.asterisk.org/jira/browse/ASTERISK-24335


Repository: Asterisk


Description
-------

Scenario
INVITE arrives to asterisk, asterisk responds Busy()
If the INVITE is retransmitted, asterisk will generate a 503 in addition to the 486.

Patch ensures a 2nd response isn't generated to an already responded INVITE
