Asterisk doesn't pickup incoming calls
after registering a phoneline, outgoing calls work fine, but incoming calls do not cause any phone (neither orbiter-phones, nor any otherwise attached phones) to ring /var/log/asterisk/full in my case states: "warning [chan_sip: username mismatch, have <fritz.box>, digest has <620>" "notice 2014 chan_sip.c: failed to authenticate device sip:01xxxxxxxxx@fritz.fonwlan.box" In my case I am connected to an AVM Fritz!Box, where Asterisk is being registered as a sip-phone with the username/phonenumber "620" The Hostname/registering Server is "fritz.box" By the way, I don't know if this is a related issue or by design: there were no firewall rules present in Webadmin, but allowing udp/tcp 5060 didn't solve the problem either
