Trying to get a phone located in another office registered to the Freeswitch server. I created an "external5090.xml" in the sip external folder as per the wiki and then set the phone to connect to 5090. But I cannot get the phone to register. When I look at wireshark I see a request from the phone to register and then I see an error "SIP:403 Forbidden" from the server to the Phone. I have created the extension in the Directory folder with the other internal extensions but I'm wondering if I'm missing something in the 1010extension.xml for it to work. (maybe the extension is located in the wrong folder, or some identification to say it is not in the local LAN?) I have checked the name and password and they are correct which seems to indicate the issue is at the server level. Any guidance on how to setup an external phone to Freeswitch would be appreciated. Thanks CJB
