[SIPForum-discussion] About ENUM

[Deepanshu]

Okey,

Thanks for you comments

But, one more issue. It is possible in IM that a user is using a PC or PDA
instead of mobile. In this case i believe he must not have a Tel:URI.
right??

So, how to do in this condition? any ideas

I c.
During the registration, the SIP URI of sender would be registered as well
as the tel URL in the S-CSCF (Implicit registration).
So the tel URL is easy to get from the S-CSCF when it's necessary (IM case).

No ENUM should be concerned I belive.

It is something related with SMS-IM interworking.

When an IM user sends a SIP MESSAGE (IMS domain) to a SMS-only user (CS
domain) then their is a need to find the Tel:URI associated with the SIP-URI
(included in the SIP MESSAGE) of the sender. The Tel:URI is needed to be
incorporated in the SMS message send towards receiver using which the
receiver can respond.

Hi

ENUM query maps a Tel:URI (008613585147627) to a SIP-URI
(sip:user at example.com). Can ENUM query work in the reverse direction mapping
a SIP:URI to Tel:URI?

In other words i have a SIP-URI i like to know its corresponding Tel:URI,
can i use ENUM query for the same.
