I setup an intercom attachment to an FXS port. This morning, one of my users placed a phone call and we heard the whole thing over the intercomm...Is it my setup?
The 2801 with FXS is in H323 mode, here's the portion for the intercom code (we want people to dial *34 for the intercom):
dial-peer voice 55 pots
description Paging for Fire
Now the strange part is, (and obviously I am changing #s a bit here to protect the innocent), my user was calling someone's cell phone and the # is sort of 686-9003, so no sign of the pattern there. Now the first time she did this and we heard the message she was leaving over our intercom, we called her and told her what had happened. So she figured the call did not get delivered, so she called the cell again. And again this time, we heard her call over the intercom! So we had her try other calls to other cell lines and POTS lines and none of those came over the intercom. So I am thinking the cell phone subscriber must have their phone setup to forward to a speed dial like *34, and somehow we see that and turn the intercom on...what is weird is that you now have 2 calls going, one to the cell phone and one to the FXS port.
Other than a FAC, any good ways to prevent this from happening? I have done lots of these setups and never had anything like this happen!
Would love any insight!
Well, when you can - if it's a dedicated interface (usually is for paging), I think it's better to have a dedicate route group and route list. The pattern you choose to access the OH system is then just pointed at that single RL. No potential confusion there. The FAC is up to you. When everyone has access to dial the paging system - FAC doesn't really amount to much (IMO) but I have customers that prefer to go that route anyway.
