asterisk users - Jun 2020 - 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

The patches to get linphone-3.12 BLF working with Asterisk are here:

http://perso.calvaedi.com/~john/linphone-3/

They're pretty damnned trivial:

1. add the "Accept" header to the SUBSCRIBE message so asterisk
doesn't
reject it.

2. don't trash the SIP dialog if the SUBSCRIBE refresh is rejected 
because of a stale nonce.

3. If asterisk says the user is on the phone set the status to on the phone.

All except the 3rd one are compatible with linphone-4. Implementing the 
same feature with linphone-4 is left as an exercise for the reader.

Version 4 of linphone is, frankly, rubbish.  I have managed to hack it 
to the point where presence shows green for connected contact and grey 
for disconnected.  However this requires setting the "send subscribe" 
flag in the linphone contacts db and linphone 4 has no UI for setting 
this flag, you have to do it using sqlite3 directly (or setting up your 
contacts in linphone 3).

Lately, I read [1].
So it seems both Jitsi desktop and Linphone are on par, on this ;-)))
