So I’m a complete newbie to IP based telephony, but I desperate to replace my old Nortel system.
Ive purchased 4 Grandstream GXP2140s and a UCM6204. I have 4 analog lines and I’ve also set up service with Voip.ms (eventually plan on ditching analog lines, but not yet…).
I’m trying to configure a test setup before I deploy to the real world. Ive hooked my main network in to the WAN port, and set up accounts. Everything seems to be registering accounts properly, but when I try to make a call I get the error ‘you are not authorized to make this call’. I feel like I’ve set dialing rules up properly, and as far as I can see have appropriate permissions set up,
I’m thinking the problem has something to with the LAN vs. WAN hookup. In my experience the ‘WAN’ port is used to provide a hookup between the internet and the device, whereas the LAN port provides local services to the network. My confusion (I think) is how this works within my setup. I’m not sure why this needs two ports in this case…can someone clarify?
