<DIV dir=ltr><FONT face=Arial size=2> I have several sites
with overhead paging systems. I have linked them to CCM using an ATA186
hooked to a Valcom paging adaptor (the exact model number I cannot remember
right now). I just put a phantom DN on the ATA and program a speed dial on all
phones that need access. They press the speed dial and are greeted almost
immediately by the Valcom "talk tone". The paticular model I am using has
feedback reduction. I highly recommend using a phantom number, because if
someone on the outside dials into it you could have a problem. This has been
working perfectly for the last couple of years. I tried to use an FXS port on a
3725 once, but I had problems with the port not disconnecting properly and
getting hung up. I switched to the ATAs and have had no more problems. If you
would like I can get the Valcom model number I am using, just let me know. Hope
this helps!</FONT></DIV>

<P><FONT size=2>After having exhausted all my normal avenues of research
(including<BR>TAC), I thought perhaps someone here has run into the same problem
I'm<BR>currently tackling. I have a site recently migrated to CCM from
an<BR>older Siemens PBX. The site has a custom overhead paging system that
is<BR>as simple as can be imagined -- tip and ring link to speakers and
when<BR>this is connected to with the old system, voice is transmitted over
the<BR>paging system. We initially thought we could just link to an
ATA-186 or<BR>an FXS port, but this thing looks like it is off-hook constantly,
so you<BR>can't only do that. I also tried to put a Valcom V-9940 Paging
Adapter<BR>in the middle, but my layer 1 skills are limited and the solution
failed<BR>(I may have selected the wrong wiring configuration). My
question to<BR>the list is, has anyone come up with a method to link CCM into
overhead<BR>paging systems, and if so, would you be willing to share your
solution?<BR><BR>Thank
you,<BR>Mark<BR><BR>_______________________________________________<BR>cisco-voip
