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).
