[cisco-voip] Remote Site phones rebooting

[Aman Chugh]

Thank you all for your help.Let me answer your questions

1. It does not happen with a single phone, it only happenns when the call is
ringing on a all phones on the shared lines and under heavy traffic
conditions when every one or majority of the users are active on the lan.
2.I did check the output of sh policy-map interface and dont see drops on
the class which is applied to signalling traffic, How do I increase the
queue-depth for a particular class.
3. I am also seeing buffer misses on my router , I see a lot of medium
buffer misses on my NMS.

I am running 12.4.3c on this router which is 2801 , This Ios had been quite
stable for an Year for me.

TIA

Aman
