BCM and Cisco Tunnels

[angulo]

SO I here is my tree:

HQ: Servers/IP phones with tunnel
HQ2: BCM with Tunnel
House: IP phones with Tunnel
House2: IP phones with Tunnel

Each location has Cisco 400 routers and they all have tunnels to each other. I really do not want tunnels to every site. The IP phones work. If I call from house to house 2 with the tunnels working, the calls go through and I can hear the caller fine. Now if the tunnel goes down between the two house sites, The phones at the site stay on because they have a tunnel to the BCM, and I can call the ip Phones but, no sound, can not hear caller. I want one tunnel to say, the BCM site which I can connect to from every site and have the phones work and calls go through. Any help is much much appreciated.

Packets for signaling go between the IP Phone and the BCM. Packets for voice go direct from one IP Phone to the other IP Phone.

Right, so are you saying the way i have it is the only way to do it, or do you know of another way with just one tunnel for all sites, instaed of 4 tunnels

You need tunnels between all sites.
