phone call through IPsec VPN

pedrobranca · ‎03-30-2009

Hi,

I'm trying to establish a phone call between two sites through an IPsec VPN. I am able to establish the phone call however the call is not going through the VPN.

My scenario is:

7960 phone --- switch --- 2811 router --- router --- 2811 router --- switch --- 7960 phone.

The VPN is working since I am able to ping from a host on the same network as the phone to a host on the other end and in the same network as the other phone, and the ping goes through the VPN.

Any ideas/solutions would be most appreciated.

Thanks.

I am assuming that your phones have an ip address within the 10.X.0.0 range for which this vpn tunnel is defined, if that is the case, how can you tell the call is not being sent via the vpn tunnel? As a little advise, I would not use AH on the transform set, it is known to cause problems.
