You can trust other proxies by checking the source IP address of the 
request.
   if (src_ip==192.168.0.10) {
     # request comes from trusted proxy
     ...
   }

You can also use the functions from the lcr module to verfiy the src IP 
address against a table of trusted IPs.

I think there are also some funtions in the permission module.

Furthermore, between the SIP proxies I would use TCP or TLS instead of 
UDP to prevent IP spoofing.
