If you want to avoid ENUM, then you should probably avoid tel: as well. Instead, use sip uris with the user=phone parameter:
REGISTER: sip:freescale.com To: <sip:[EMAIL PROTECTED];user=phone> From: <sip:[EMAIL PROTECTED];user=phone> Contact: sip:[EMAIL PROTECTED]
I don't know what value user=phone adds here.
Its value is to say that what is in the user part is a phone number.
3261 has defined two namespaces for the user part, distinguished by the value of the user parameter, so it is good to be clear about which namespace is being used.
Of course many systems don't really have two namespaces, and instead treat them as equivalent. If so, then it doesn't matter if you specify it or not. But unless the UA is certain about the conventions of the registrar it is safe to be explicit.
