First thing, I had a company IP phone project dropped on me, I am a all in one schmuck.<\/p>\n
I am using a Grandstream UCM6304A, with Glo Fiber as my provider.<\/p>\n
I am completely and utterly lost with the simplest step of this, registering the SIP trunk.<\/p>\n
They have their NID at my location. Port 1 is for my internet port 2 for the SIP. I have a TZ470 as my firewall. I will be setting this up to hit multiple site to site vpns (I have this working as far as handing out ZC etc)<\/p>\n
I have the SIP port from the NID going to my UCM wan port, lan port back into my switch.<\/p>\n
The proxy server is the same as the DNS server as far as the URL goes<\/p>\n
I have tried setting up the Network settings in the UCM as switch mode- cant access my UCM after setting the UCM IP.<\/p>\n
Route mode- setting the static IP info with what the ISP has provided me I simply cannot get a connection.<\/p>\n
All of the IP info they have provided me are all internal private addresses. They came out and placed an ADTRAN on a different port on the NID and was able to register immediately.<\/p>\n
I have taken my FW out of the equation and went into my pc with the lan port and nothing as well, so I do not believe the issue lies with the firewall. It has to be something with the UCM settings that I just cannot find or locate. ISP is unable to provide any help whatsoever. I have enabled the Outbound Proxy Support in the SIP trunk settings and entered the proxy they gave me, i have tried it disabled<\/p>\n
I know it has to be something with the way this needs to be setup when given private/internal ips vs public ones. Anyone able to help a guy out before he loses his mind?!<\/p>\n
ISP has provided me with the following<\/p>\n
