I wanted to get back to the group to explain what happened in case anyone is searching in the future. Client had a sip trunk coming in on a port with data. Vendor required him to use one of his public IP for the SIP trunk. No authentication, they limit the SIP traffic from his public IP only as their security. Had the normal turnup call. Because of the lockdown, I wasn’t on site, relying on local IT to plug the wire from the ETH1 on the PBX to the 5 port basic switch that his data connections already were plugged in. Its his backup data from this vendor. Interface showed connected, I setup the static IP, etc. Some traffic seemed to move, some didn’t. I could ping the SIP gateway address fine. Calls still weren’t moving in or out. Vendor was sending option pings and not showing a connection. My side showed “unreachable” when I would set “qualify=yes”.
End result was that the switch was bad. I had local IT plug a PC into the switch and assign the public IP to it and he couldn’t go anywhere either. Then had him remove the switch and plug the PBX directly into the AdTran and calls instantly started moving fine. So, the switch showed a connection, seemed to ping OK, but wouldn’t work long enough to get the trunk up and running. Thanks to all that helped, sometimes the simplest thing is the easiest.
