Hello,

Some comments inline:

Christer has pointed out, that the use of any parameters in the user-part may mess up the implementation.
Is there something in the bis doc, that says its not a problem? 

>  We are not discussing how those tel URL extensions can be carried as the url-parameters, that is

Would not you want to describe this possibility in the draft?

What are the main concerns about transferring this extensions as SIP url-parameters?
