[SIPForum-discussion] Remote Party ID (RPID) missing for Restricted call (caller ID hide)

[Shakil, Rashid]

Hello all,

 

Quick question please ...Can any SIP peer allowed to send an INVITE for
restricted call without calling FROM information with no "Remote Party
ID". If you look at the following information calling From number is
restricted and "Remote Party ID (RPID)" is missing as well therefore no
way to find out where the call is originating from. Is this acceptable
if yes can you please reference a draft where I can read this in detail
?
