I would like to connect a paging system to Cisco Call Manager 6.1. I have a router 2811 with FXS and FXO ports. The manufacturer of the paging system told me that his system acts like a telephone system, so it should be connected to FXO. The available settings on the paging system are:
- C-wire is stand-by current <-> operating current
- connection is subscriber <-> cross-connection, exchange line
- loop current is provided internally <-> externally
The above is translated from German, thus I am not quite sure about the technical terms. The question is which settings should I choose? Next, what is appropriate for the FXO? Currently I have:
signal ground-start
cptone DE
impedance complex 2
timing hookflash-out 50
I have configured a route-group, a route-list and a route pattern. When I dial the number the LED at the FXO interface is lit shortly and I get a busy-signal.
Any ideas?

Hi Christoph,
I think a good first step would be to choose;
signal Loop-start
I can't see the Paging system using Ground Start.
Hope this helps!

It turned out to be a simple POTS, thus no FXO port but a FXS port was required (in contrary to what the manufacturer said). If found it when I started to measure voltage...
The "no battery reversal" was necessary, though.
