[Freeswitch-users] RPORT still being sent in TCP calls

We have noticed that FS is sending RPORT in TCP calls to a gateway. It was reported as fixed in this bug: https://freeswitch.org/jira/browse/FS-6612 We are running: 1.5.15b+git~20150512T053645Z~9eb887af47~64bit I am not sure why RPORT is still being sent. Is this there a config parameter which needs to be set to suppress the RPORT? Or was this change reverted in later versions for some reason. Provider is telling us we should not be sending RPORT in TCP... Any info would be greatly appreciated. Thanks!
