[asterisk-users] How is automatic redial/callback when available implemented ?
Hi, A theorical question : For some SIP hardphones (or mobile handsets), when receiving a busy response, it is possible to ask for automatic redial and your phone will later try to call your contact. As I'm wondering how I could provide a way to cancel those automatic redials, I'm trying to understand how it works. My question is : 1- do SIP hardphones usually wait for some input from Asterisk (when AutoRedial is asked, a SUBSCRIBE is sent to be notified of status changes) 2- do they redial on their own, after a waiting period, 3- both ? My testing would show 3 (but I'm far from certain) as : - I saw SUBSCRIBE messages flowing - the first redialed even when then the other end was kept in a busy state Regards -------------- next part -------------- An HTML attachment was scrubbed...
