Hi guys,
I have an ongoing issue where some internal extensions fail to connect to other internal extensions. The agent making the call can hear the recipient but the recipient cannot hear the caller even though the call connects. I have found a work around to this problem by flashing the IP sets and downloading the latest firmware. This solves the issue for a few days and then it reoccurs.
IP sets: 5010 & 5020 IP handsets
Console: 3300 ICP
