Thank's for your help Raj I tried your configuration with a slight modification to the current IP from Alcazar. This didn't work because it said it didn't recognize </gateways>. Didn't even load into sofia. So I removed the extra data most likely specific to your set up. And got this: <include> <gateway name="alcazarnetworks.com"> </gateway> </include> This should be a simply stripped down version of yours so that should work but it isn't. Any ideas? I'm sure I made some stupid mistake that I'm missing. -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/External-SIP-Trunk-IP-Authenti...
