[Users] new version openser how to deal with call a SIP uri with multi registar

[Bogdan-Andrei Iancu]

Jimmy,

for parallel forking you do not have to d anything special - fir this 
purpose you don't need a failure route. Just do lookup() and t_relay() 
and that's all. Failure routes are usually used for serial forking.

For serial forking, you can find of cvs some basic example in 
"examples/fork.cfg" or something more complex at 
http://www.voice-system.ro/docs/avpops/ar01s08.html#ex_serial_forking

regards,
bogdan
