Subject: [Sipping] REFER usage in multiparty application and call control

Hi all,

I have a question regarding the use of REFER in peer to peer multiparty
applications and call control.

Say a UAS receives a REFER, how would it distinguish a REFER used for
multiparty application from a REFER used in call control? 

Or, to put it differently, do we really care if the REFER is different?

Thanks.

Aaron
