[Freeswitch-users] Making calls without a gateway

Hi list I can make calls via a gateway, but am a bit stuck when making calls directly to sip provider. They accept IP authorization. I am using the following syntax. <action application="bridge" data="sofia/external/617$1@X.X.X.X:5060"/> I get [INFO] mod_dptools.c:2579 Originate Failed. Cause: NETWORK_OUT_OF_ORDER and on the phone I get BAD Gateway. When I use asterisk to the sip provider it works fine. Greatly appreciate any pointers. Regards Kilburn
