We have a remote office 7000 miles from our HQ, phones are in teleworker, MBG is in HQ, my issue is that phones keep getting disconnected, it happens very randomly 2-5 times a day, but it happens with all phones at once, typically the phones get reconnected after a few seconds,
I monitor the network traffic, we don't lose any ICMP traffic., I do see in the firewall logs TCP Client/server reset.
Any suggestions?
