[asterisk-users] linphone calls not missed due to cause not 487

Calls cancelled by caller during the dialing phase, are shown in 
Linphone as simply past calls, not missed ones.

I thought this is an Linphone issue, but Sylvain says it's on my PBX side:


 > The CANCEL message has a Reason header with Q.850 protocol and cause 
0, which doesn't mean call has been missed (should be 487).

Is this my dialplan / setup or an Asterisk issue? How can I get Asterisk 
to send cause=487?
