Hi,

I wonder if anyone could give me some light regarding the following

In one site I have a 2811 and in the other site I have a 2811 with a PIX506E.

Both routers are running CallManager Express with IOS versions:
c2800nm-adventerprisek9-mz.124-4.XC4.bin
c2800nm-adventerprisek9-mz.124-4.XC.bin

The site to site VPN is up and working. I can do a
ping 192.168.1.1 source 192.168.0.2
and get 4 replies back.

Also, I can place any calls, from any of the two branches ok. It is only when I try to phone an extension number of the other branch that I have problems (i.e. 2106). The phone rings, and even recognises who I am phoning on the other branch but when the other person picks up the phone I can't hear them and they can't hear me.
I have set the dial-peer to send the traffic accross the VPN on both routers. ie.:

dial-peer voice 10010 voip
destination-pattern 21..
session target ipv4:192.168.1.1
dtmf-relay h245-alphanumeric
codec g711alaw

Thank you for any help
