I don't remember full details, sorry, I believe, on linphone app there was no video at all without this option.1) why is that canreinite important?
The reason could be that my asterisk server is sitting behind strong NAT without white IP address.
Probably you can find some explanation here Asterisk sip.conf canreinvite option
Yes, all online phones ring simultaneously. If nobody pickup the call within 30 secs or all ## are offline, asterisk start calling next linphone #.2) in your dialplan, if you call 101 , do 101 and 102 and linphone user all ring simultanously? i thougth that that didnt work, that only 1 extension was ringing , if 101 is not avaible , then goto 102
So do they all ring at the same time? and with early vidoe?
For the early video I have to double check. But it definitely come to my phone (#102) and firstname.lastname@example.org, if I'm away from home.
Honestly speaking, I didn't make any sip.linphone.org specific setup. It just works out of the box.3) i also see you call externally a linhone user based on sip.linphone.org, how do you that ? i also call linhome users; i created an outbound trunk that registers on linhome flexisip, with that trunk i do an outbound call
