Maybe :) > Is there any draft or RFC in which this behavior is defined? RFC 3265 section 3.2. However since the NOTIFY likely has no To tag, it hard to claim that it is compliant even though it is/was common behavior. You might want to look at this "NOTIFY without SUBSCRIBE" thread from 2007. https://lists.cs.columbia.edu/pipermail/sip-implementors/2007-December/018048.html _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
