Hi, RFC 4916 just handles "From" header, but what about if the initial request or in-dialog re-INVITE/UPDATE (RFC 4916) contains a P-Asserted-Identity header?
For example, if a B2BUA sends INVITE to phone A like: INVITE sip:[EMAIL PROTECTED] From: sip:[EMAIL PROTECTED] To: sip:[EMAIL PROTECTED] P-Asserted-Identity: tel:+1234 Supported: from-change then phone A should render "1234" as callerid (if it supports it of course). Imagine B2BUA sends now an UPDATE like: UPDATE sip:[EMAIL PROTECTED] From: sip:[EMAIL PROTECTED] <-- CHANGED To: sip:[EMAIL PROTECTED] (no P-Asserted-Identity header) Should then phone A render "sip:[EMAIL PROTECTED]" as callerid? or still "tel: +1234"? And what about if the UPDATE contains again "P-Asserted-Identity: tel:+1234"? IMHO the normal behaviour is that original "P-Asserted-Identity" should remain rendered but it makes impossible to update the callerid if needed. Thanks for any clarification. -- Iñaki Baz Castillo [EMAIL PROTECTED] _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
