thanks for responding
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.
thank you for your input
