[SIPForum-discussion] both TEL and SIP URI's in the request line

[Pranav Damele]

Hi Manoj,

You cannot have more than one URI in a SIP request line. It does not make
any sense logically. And syntactically also only one Request-URI is
permitted per SIP request and one URI scheme is permitted per Request-URI.

Request-Line = Method SP Request-URI SP SIP-Version CRLF
(where SP stands for space)
e.g. OPTIONS sip:+911234567890 at 10.20.30.40:5060;transport=tcp SIP/2.0

e.g. OPTIONS tel:+911234567890 SIP/2.0

But you can have different URIs in you SIP message header
eg. P-Asserted-Identity header having tel-URI and another
P-Asserted-Identity header with SIP-URI in the same SIP Request.
