Subject: Clear the high order bit from the destination call number before sending.
X-Git-Tag: 1.8.11.0-rc1~42
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=94ade43b564385004be12d86ba8d61367f85f6a1;p=thirdparty%2Fasterisk.git

Clear the high order bit from the destination call number before sending.

send_apathetic_reply takes the incoming frame's source call number as the
destination call number for the outgoing frame.  If the incoming frame was a
full frame, then the high order bit of the source call number is set and will be
interpreted as a retransmit when sent back out as the destination call number.
