[VoIP] Setting CID in *

[John R. Covert]

I realize that this won't work if your switch does not do proper
answer supervision, but if it does, be sure you always put a
timeout of something like 120 seconds as the second parameter
of the Dial command.  That will make sure that something doesn't
go wrong (after all, not everything is malicious) and keep one of
your RNA numbers ringing all night.
