Hi, I'm trying to send multiple Direct Indial Numbers down to a dynamically registered SIP User. I need to ensure that both the To and Target URI contain the direct Indial number. I'm able to modify the SIP TO Header of a call that is sent to them like below: <action application="bridge" data="sofia/external/56778977%${domain}^61390009000"/> which sends the request as: ------------------------------------------------------------------------ INVITE sip:56778977@192.168.22.2:5061 SIP/2.0 Via: SIP/2.0/UDP 202.0.155.73;rport;branch=z9hG4bKXeND9cHtgKF2j Max-Forwards: 69 From: "0390001000" <sip:0390001000@192.168.2.200>;tag=K4HHaZ9v1H07Q To: <sip:61390009000@192.168.2.200> But in order to maintain compatability with a number of PBX's/VoIP devices on the market, I need to be able to send the invite to the dynamically registered SIP user, however have it set the Target URI and To as the same contact number like below: ------------------------------------------------------------------------ INVITE sip:61390009000@192.168.22.2:5061 SIP/2.0 Via: SIP/2.0/UDP 202.0.155.73;rport;branch=z9hG4bKXeND9cHtgKF2j Max-Forwards: 69 From: "0390001000" <sip:0390001000@192.168.2.200>;tag=K4HHaZ9v1H07Q To: <sip:61390009000@192.168.22.2:5061> Is there a way to do this setting via variables? I can't seem to find any details for it. Thanks David
