Re: Bridging between two routers

Why do you need to configure bridging in first place ? That usually brings to trouble and more trouble.

Re: Bridging between two routers

Bridging is not supported on tunnels. If you really need to do this, you need to look at L2 VPN tecnologies, ut as has already been said, SIP and associated protocols are designed to work over routed networks. Yu need to figure out the real problem.

In this configuratin, when SIP Proxy and ip rhones have diferent network, voice is not work. I think that bridge help us.

No, SIP is designed to work on routed networks. You have a different problem, either in network, or telephony devices.
