That’s a really old version of FreePBX - you might want to schedule an update for your system to get you onto a more recent version (We are on version 15 now with 16 looming large on the horizon).
Since this isn’t actually a Digium forum (and this looks like a Digium problem), you might want to submit a ticket on this.
Finally, on the chance that this IS a FreePBX problem - we’re going to need to see some kind of logs on what’s happening when these phones fail. I’d guess (which is what I do) that you’re NAT associations are failing, but I just hang out here, so I could be completely wrong.
agreed we need to schedule a upgrade soon, it is difficult to get the downtime and it works so well.
also agreed this is most likely not a Freepbx issue. we have 300 plus phones and it is only happening on a few.
It wasmy hope that someone has experienced this before and could provide insight on what to look for.
i will try moving one to a different switch, of the phones i have this issue on (that i am aware of) there are 2 that only have one phone on each of the switches.
the other location only has one switch (connected by a 1000 mbs layer 2 circuit)
the switched are one HP 2910, and 2 hp 2930. the 2910 has about 15 phones connected to it.
this is very odd as i have a number of locations across the country with the same setup and this is not an issue.
This issue is very random and go for days without happening.
