[cisco-voip] VG224 and Call boxes

[Fuermann, Jason]

I wish it were that simple. We've tried these in our telco room with a PSTN line and they work fine, but as soon as we switch back to the VG we get the disconnect problem again

We've had similar problems and it ended up being the contacts on the button
of the call boxes.  Some contact cleaner and contact grease fixed the
problem.  The problem tends to arise when seasons change or humidity levels
change.

Call boxes, essentially speakerphones that autodial a number when you push a
button. Also, yes if we use a butt set or connect a regular phone to the
line, it works fine.

Jason,
   What are these "boxes?" If you replace them with a cheap analog
phone, can you reproduce the problem with that?

the call is answered at our PD. These had been previously working fine, and
the vendor even says that the VG224 is compatible with them. The only change
I know about that occurred was we rebooted all the nodes in our cluster and
the vg224 gateways as well. The CDR's show a disconnect code of "unknown" so
I'm thinking that maybe this is a supervisory disconnect from the gateway.
Does anybody have any ideas on what may be going on?
