Summary:                    TCP calls no longer bridge (last working version was
1.6.0.1?)
Description: 
When dialing Microsoft Exchange server (which requires SIP over TCP), the
call no longer bridges.  To my knowledge, this works in 1.6.0.1 but not in
1.6.0.14, 1.6.1.x or 1.6.2.0

tested on CentOS release 5.3 2.6.18-128.2.1.el5
