[SIPForum-discussion] how does a SIp UA handle INCOMING tel URI

[Cowby]

Hi,

I have few question about "tel" uri defined in RFC 3966.

Q1: is it possible that a SIP UA can receive incoming requests with tel uri
as the request-uri?

Q2: if the answer to Q1 is yes, how does a SIP UA normally handle tel uri to
match the UA itself?

For example, if a UA has a mailto:"sip:cowby at cows.com' as its IMS public
identity and +1-408-555-6666 as it global phone number,

Q1: is it possible that the UA's P-CSCF can route an INVITE
tel:+1-408-555-6666 request to the UA?
Q2: how can the UA match itself when it is configured as cowby at cows.com but
know nothing of its phone number?

Thanks.

Cowby
