[cisco-voip] FXO port ignore incoming

This is what I ended up doing. I did connection plar (non-opx) and put ring number to max, which is 10 (on my platform at least). Not quite what I was looking for but close enough. Realistically, if nobody answers after 10 rings then they are probably not there to notice the issue anyway.

Still feels like there should be a better way though... is it really that unusual to want to use a port only for outgoing?

Under the FXO port try "ring number x" where x is how many times the port should ring before VG answers it. I don't have a VG at hand right now to see the max value of rings possible but it could accomplish what you need.

Unfortunately the gateway in question doesn’t have any FXS ports in it. If I have to resort to doing plar opx to somewhere that never answers, ideally the “somewhere” should not require any hardware.

During normal operation, the analog line is just for outgoing local 911 calls. Incoming calls come via WAN from the PRI at another site. But the telco rings the local analog line simultaneously with the PRI. During power outages, staff plug in a POTS phone in order to get the incoming calls via the analog line. During normal operation I need to ignore the ringing on the analog line so that calls don’t all show up at the PBX twice.

OPX to an FXS port maybe?

I'm curious what the use case here if you never want it to answer.

I need to make an FXO port ignore incoming calls. I.e., don’t take the trunk off-hook, and don’t make any phones ring. Just let the trunk keep ringing indefinitely.

What is the best way to accomplish this? I could swear I’ve done this before, but I’m drawing a blank at the moment... connection plar opx to somewhere that never answers? There must be a better way than that.
