SIP over TCP

Hello All

Does SIP over TCP supported in AsteriskNow 1.5 (FreePBX)?

please advise

thanks & regards

Has anyone got this working. I am Running Elastix 1.6-12

I have added the following to /etc/asterisk/sip_general_custom.conf
tcpbindaddr =
tcpenable = yes

and created a trunk (Which shows connected to the exchange server)


I have also set my Exchange 2007 server correctly but the exchange server will not register on the Elastix box.

Exchange error is

The IP gateway or IP-PBX “*” did not respond to a SIP OPTIONS request from the Unified Messaging server. The error code that was returned is “0” and the error text is “:Unable to establish a connection.”

When i run NETSTAT -ln on the elastix box it only shows the UDP port that is open and not the TCP SIP Port 5060

Why is elastix not starting TCP SIP?
