On a new installation we see that zulu stops ringing after 15000ms if the user doesn’t pick up.
-- PJSIP/90280-000010ac is ringing -- PJSIP/90280-000010ac is ringing -- PJSIP/90280-000010ac is ringing -- Nobody picked up in 15000 ms -- Auto fallthrough, channel 'Local/90280@zulu-call-0000243c;2' status is 'NOANSWER' == Everyone is busy/congested at this time (1:0/0/1) == Spawn extension (zulu-desktop-phone, 90280, 7) exited non-zero on 'Local/90280@zulu-desktop-phone-0000243d;2'
If the user picks up within that time there is no issue.
The desktop phone keeps ringing if the user has one. I guess a timeout is reached after 15000ms but I can’t find it.
