I do it on my SIP phone all the time. I can put ANY SIP URI I want.
If it's a phone number, phone will append the default domain of the phone. The other phone then INVITE the contact. The enterprise proxy looks at the phone number and then decides if it owns it (e.g., it could be another phone number of a phone in the enterprise). If it owns it, it will route the INVITE to that phone. Never goes to PSTN. If it does not own it, it will route to the appropriate PSTN gateway (based on least cost routing for outbound PSTN gateways and such). That's what happens when I forward to my cell phone. The point of this story is that when ;user=phone is used, the routing is based on the phone number. Like it or not, this is what seems to happen. In other words, it's a functional equivalent to a Tel URI. There is a reason why people do it like this. Try sending a Tel URI on the wire and see what happens with most equipment out there.
