True Dave. There are a fair amount of constraints that have to be applied on a per hop basis but it does scale.   I would say dialing a phone number is pretty casual interoperation.. ☺ 

SIP URI as identifiers never took off [ yes Virginia Telephone numbers are still  here) but its use in core carrier networks along with the 3GPP IMS super set is now dominant.  In the US that is now about 40% of all Voice minutes in the interconnected Public SIP Telephone Network aka PSTN. With VoLTE it will be nearly 90%.
