I've got 3CX (currently free version to test it out and work out some of the kinks) 6.0.806. I've got a couple of Linksys SPA962 phones. Each has two occurrances of the phone extension (711 on one and 712 on the other) and then a single occurrance of a second extension (731 and 732, respectively). I've got two SIP trunks from InPhonex. I've got four SPA3102 devices connected. One goes to a business POTS line. Two go to Vonage lines via the Vonage adapter (basically, POTS). The fourth goes to a home POTS line. I've got a couple of different ring groups configured, one that rings the "main" extensions and another that rings the "secondary" extensions. I've also got an auto-attendant chain configured to do various things (answer and give the greeting, allow hitting a key to get right to an extension, ring the "main" extension group, etc.). All lines are set to go to either the day or night auto-attendant except the fourth SPA3102. Instead, it is set to go to the hunt group that rings the "secondary" extensions. So in theory, if someone calls on the Vonage lines, the InPhonex SIP trunks, or the business POTS line, they'll get the office auto-attendant. If someone calls on the home POTS line, it would ring on the secondary extensions on all phones and that's about it. However, for some reason, if I plug in the home POTS line to the proper SPA3102 and try to call on it, it goes straight to the office auto-attendant. It is NOT configured to go there within the PSTN gateway configuration in 3CX but it is anyway. I've rebooted the 3CX machine to no avail. If I unplug it, then it obviously just keeps ringing when I call that number from outside. This is driving me nuts! Anyone got any ideas what might be causing the problem?
