[Freeswitch-users] Making calls without a gateway

[Kilburn Abrahams]

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 at 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
