Hello,

with IPSec you need to define all the networks that are going over the VPN, this can become complicated, so if you configure the minimum on the ASA/PIX to build a GRE tunnel between the routers, the all the address will pass undisturbed and everything will work.

Hope this helps, plase rate post if it does!

On ASA where there is a ip phone network:

access-list inside_nat0_outbound extended permit ip IP_PHONE_NETWORK

255.255.255.0 LAN_REMOTE 255.255.255.0

access-list outside_20_cryptomap extended permit ip IP_PHONE_NETWORK

255.255.255.0 LAN_REMOTE 255.255.255.0

nat (inside) 1 IP_PHONE_NETWORK 255.255.255.0

On remote office (PIX)

access-list inside_nat0_outbound extended permit ip LAN_REMOTE

255.255.255.0 IP_PHONE_NETWORK 255.255.255.0

access-list outside_20_cryptomap extended permit ip LAN_REMOTE
