[cisco-voip] VG224 and Call boxes

[Fuermann, Jason]

We have a bunch of call boxes that have suddenly started to hang up when 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?
