Packet loss and phone cut-out

We are experiancing a few phones at 1 location that are cutting out during a internal or external call. If you hit the ? twice during the call all the phone effected are experiancing a lot of packet loss. Sometime the effected phones will also re-register with CallManager on their own.

Re: Packet loss and phone cut-out

Hi,

Do you have QoS in place between the sites? Looks like you are seeing the correct results and there is a network problem taking place.

Regards, Avner.

Re: Packet loss and phone cut-out

What is the current BW to that location?

Do you have QoS configured fro Call Signalling and Voice ?

Which type of link? VPN,PPP,FrameRelay,ATM, Internet?

Phones running latest phone load?

In EV what is the reason code for unregistration?

Let us know

Re: Packet loss and phone cut-out

The problem is at the Corporate office local to all servers including Call Manager. I do have auto QoS on the 4500 switch that these phones are plugged into. I have 250 additional phones at the same location that are not having any problems. I found documentation on Cisco's website that states a network problem but, nothing in the network has changed. A network problem is kind of a general error.
