MWI-related SUBSCRIBE message to send NOTIFY messages changing phones MWI status. This is fine for me but I'm wondering what if I were using SIP hardphones refusing any such NOTIFY without prior SUBSCRIBE (does such phones exist ?) ? 1. In this case, which URI shall use a hardphone to build its SUBSCRIBE message ? Here is a hand written example. Which value should I substitute to foo (in this example) to receive NOTIFY (as if I had typed mailbox=7533 in sip.conf) ? Obviously, typing 7533 gets a "Received SIP subscribe for peer without mailbox: 7533" as if mailbox=7533 was not only used for MWI but also as a check for a mailbox's existence (though corresponding mailbox is defined in voicemail.conf).
