<div>Thank you all for your help.Let me answer your questions </div>
<div> </div>
<div>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.
</div>
<div>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.</div>
<div>3. I am also seeing buffer misses on my router , I see a lot of medium buffer misses on my NMS.</div>
<div> </div>
<div>I am running 12.4.3c on this router which is 2801 , This Ios had been quite stable for an Year for me.</div>
<div> </div>
<div>TIA</div>

<p><span style="FONT-SIZE: 11pt; COLOR: #1f497d">It might be an IOS bug on the remote site router. We used to have remote site phones rebooting issue when users put phones on-hold. We use Cisco 851 router at remote site using IPSEC tunnel. After we upgraded the IOS on remote site router, the problem was fixed.
