I have a production server running with about 90 Cisco 791’s and SIP
release 8.5(2)SR1 from last year. I was running Asterisk 18.104.22.168 and
upgraded last night after hours. (Seemed low risk to me!)
Much to my surprise, not a single one of the Cisco 79XX phones would
register. Since it’s a production server, I rolled back to 22.214.171.124 and
everything was fine. All my Linksys SPA phones and Polycom speaker phones
registered just fine.
I am now setting up test servers with both 126.96.36.199 and 188.8.131.52 to collect
I am just curious has anyone else had SIP issues with these phones and
updating Asterisk broke them?
I will post results of my findings after I have time to collect them.
