[Serusers] How to forward the call to asterisk voicemail box if no one answer the phone?

I did read this part of example. It uses append_branch() function and you
have to specify the URI which include the dialed number to use it. Is there
any function like forward() I can use so I only need  to give the IP:PORT
and use whatever the dialed number in the original uri in falure_route[1]?
