Let me start by saying that I'm a computer guy, not a phone guy......
We purchased two SPA-3102's for a client, for connecting his home office phone to his main office phone system. I configured the two SPA's here at my office, based on recommendations from the VOIP reseller. Here at the office, they worked perfectly. I then shipped the units out and have them online at the client's office and home, but they don't work at all. A call can't be completed to or from the home office.
Here is the set-up/details:
-Both SPA's are hooked up, via their internet ports, to the client's internal network
-I can PING both units and get to their admin web pages
-The home office and main office are linked by a firewall-based VPN tunnel, with all ports open in between
-The SPA at the home office has an analog phone plugged into it
-The SPA at the main office has an analog extension, off their phone sytem, plugged into it
-When picking up the home office phone you get a dial tone, but dialing an extension or phone number produces nothing
-When dialing the home office extension, from their main phone system, it just rings (but no ringing is shown on the home office end)
I haven't been able to find any diagnotics, logs, etc. that can help me determine where the issue is. Would anyone have any ideas where I might go from here, other than giving up on these units?
Thanks very much,
