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]?

I am using asterisk as my voicemail system and ser as my sip server. It works fine for a specific called number(4243) by using append_branch() function. But I don't know how to setup ser to forward any called number to asterisk if no one answer the phone. I mean something like forward() function so I only need to specify the IP and port of asterisk.
