Yes. But we need a function for the failure route to distinguish SIP 
failures (404 ...) from transport failures. Further, it would be nice if 
openser would process ICMP error messages for faster failover.

Also we need different timer for:
  - SIP timeouts: e.g. a timeout if the callee does not pick up after 1 
minutes of ringing
  - network failures: i do not want to wait for 32 seconds till my proxy 
tries the next server
