Ok, thanks, that's clear and obvious.  Now I have to go beat up(*) the 
linphone people.

((*) in the nicest possible way of course).

Ok, I've had some back and forth with the linphone developers and they 
contend that although the sequence number on the 2nd and 3rd SUBSCRIBE 
messages start a new sequence this is legal as it is a new conversation 
-- the "tag=" on the From has changed.

Are they right?  (Notice that the tag= from asterisk also changes).

It's possible. If I recall chan_sip is extremely forgiving with matching
things, so it may not have taken that into account.

[asterisk-users] Attempting to get BLF working with linphone

Hi John,

1. Could you get any further, in your quest for working BLF with linphone ?
2. Have you tried with a different Linphone version (4.12 is pending on
Linux, packaged as an AppImage, or 4.11 exists on iOS/Android/Win10) ?

Best regards
