Questions regarding tel URI

Hi All,

 &nbsp; I have some question regarding the role of  proxy/Registrar in case they receives a request containing <tel:&gt; URI .

 &nbsp;  Is it possible to get the <tel:&gt; URI  in messages other then INVITE and REGISTER or in responses of any type?

  1. From RFC 3261 it has been mentioned that <tel:&gt; URI could be present in REQUEST URI , FROM and TO header, and only for REGISTER method it could be in CONTACT header. Is it possible to get it in any other header except from these?
  2. Is it alright from implementation point of view to register the <tel:&gt; URI's just like sip URI .
  3. if the answer of previous question is yes, then if we are storing only <tel:&gt; URI of a sip-phone/ PSTN-gateway , how is it possible to map <tel:&gt; URI to sip uri if the proxy have no prior information about sip URI of that endpoint .

in my opinion the sip-phone/PSTN-gateway must have to register there sip URI's with DNS by any other mean and proxy can contact that DNS for any mapping using ENUM, please correct me if I am wrong ?

 
any help regarding the same will be highly appreciated .Please excuse if I had not formed my question's well.

 

Thanks &amp; Regards,

Parveen
