[cisco-voip] overhead paging system integrationWe would like to know more
about the setup using the ATA186 and a Valcom paging unit. Can you please
provide the Valcom model number and any setup details you care to share.

Thanks,

  Mark,

      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!

  Jason

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

  Thank you,
  Mark
