I’ve used some extensions with 2 end points registering to the same extension for a long time with no issues. Both phones ring at the same time and the other quits ringing when the other answers.
Lately I have been testing some new phone models and they’ve been a little flakey and worse, they seem to be affecting the reliability of other phones which previously worked fine without issue.
What’s happening is with 3-5 phones registered to the same extension with PJSIP, random phones will just quit receiving calls even though they’re still registered. I haven’t dug as far as I can on this yet and I intend to but… In the meantime I just wanted to see if anyone ever sees issues like this when using more than 2 or 3 phones registering to the same extension.
I honestly have no idea and don’t really think it’s a PJSIP or Asterisk issue or my config on Asterisk but, the fact that other phones that worked before, started getting flakey, I’m starting to wonder.
I am aware of all the usual suspects when a phone quits receiving calls such as NAT/Firewall issues and pin holds closing up etc. But, the phones are all the same brand and the configs on the phones and on the Asterisk side are all the same. All of these phones are all on the same LAN behind the same NAT and router/firewall. They all connect to the same Asterisk server out on the internet that lives on a public IP and no NAT involved on that end. This same Asterisk server reliably runs over 100 phones of the same brand with the same config with no issues on a daily basis.
Just fishing for ideas I guess, it’s possible these new models just suck and that’s fine but I can’t understand why they would affect other models that never had issues receiving calls before.
Thanks in advance for any help anyone can provide.
