[Freeswitch-users] New provider based on asterisk instructions (xnet/worldxchange in New Zealand)

Hi, I'm trying to set up a new provider, based on the instructions they've provided for Asterisk. I'm primarily interested in inbound calls for now. I've set up new providers a couple of times before, but my guesswork isn't working out this time. I'm getting a 404 error. The instructions say: Edit your Sip_additional.conf file and add the following: [VFX] type=peer fromuser=DIDnumber host=pan.wxnz.net insecure=invite,port canreinvite=no nat=yes secret=PASSWORD username=USERID register=DIDnumber:PASSWORD:USERID@pan.wxnz.net/DIDnumber I suspect the problem is to do with the register line, any ideas on how to set that up in FreeSwitch? Or any other suggestions of settings I ought to try changing? Cheers, Fraser
