The only remark here is that user=phone should only be added if the
ruri-user is actually a phone number. Of course that's always a bit hard
to tell in a generic SIP environment, but you might want to check for
chars in $rU and only set the parameter if it at least looks like a
phone number, and/or if you know by other means that it's really a phone
