Gotta be a config somewhere that needs to be twiddled. Is the POTS into the device at 48/56 volts on hook? If not it may think the line is off hook. If you get POTS from an ILEC it will probably have that voltage, but if you get it from an ATA or some other method it may be too low.

I'm assuming it can since calls to the office go to the phone correctly. This is an in-office setup only. No sip trunks, just a few analog devices on FXS ports on sip gateways, and some sip android clients that register directly with the UCM6104. josh reynolds :: chief information officer spitwspots :: www.spitwspots.comOn 12/29/2014 12:36 PM, Chuck McCown via Af wrote: Is the trunk (FXO) actually connected to a POTS line? Does it try, like can you monitor the POTS line and hear it go off hook? Can you make calls to a sip trunk? From: Josh Reynolds via Af Sent: Monday, December 29, 2014 2:25 PM To: af@afmug.com Subject: [AFMUG] offtopic - grandstream analog trunk Anybody here have any tricks for getting a UCM6104 to use the damn analog trunk? The trunk is configured, no password on it (have tried with and without). Basic call routes have been configured including a catch-all, but whatever I do no phone will actually use the analog trunk(s). Any pointers?
