[OpenSIPS-Users] 408 timeout

[Bogdan-Andrei Iancu]

Hi,

OpenSIPS is generating the CANCEL due to the timeout (no answer to the 
call) - see:
http://www.opensips.org/html/docs/modules/2.2.x/tm.html#fr_inv_timeout

If you want to get a redirect to a VM, you need to use the failure route 
in order to catch the 408 reply and create a new branch to the VM server.
