Summary:                    Asterisk drops call leg to Cisco while other leg
remains up.
Description: 
SIP/1102 is SPA962
SIP/cisco is Cisco 5400

SIP/1102 calls to Cisco through asterisk. When call is answered on the
cisco side asterisk drops call leg to cisco while call leg to SIP/1102
remains active.
I attach full log of such call with debug level 10 and sip debug enabled.
You can see that asterisk sends BYE to cisco even before writing to log
"SIP/cisco-00000008 answered SIP/1102-00000007"

This is a regression since we have been using this gateway with previous
versions of asterisk without any problems. I've tested 1.6.0.17 with the
same configs and asterisk doesn't drop call.

Additionally, Asterisk versions 1.4.27.1, 1.6.0.19, and 1.6.1.11 also
contain an
SDP regression fix as described in issue
https://issues.asterisk.org/view.php?id=16268.

After this bug fix AS5400 work is fine.
