I now have multiple sites doing this at random times.
one is a 6208 running 18.104.22.168
one is a 6102 running 22.214.171.124
I haven’t put anyone on 1.0.19.x yet
After upgrading the phones to 1.0.9.x (I don’t know if it was 126.96.36.199 specifically or just 1.0.9.x in general), an incoming call will randomly drop. Most often right at the moment of answering. The customer will answer the ringing call like normal and just hear a dial tone when they pick up. The person calling in simply gets hung up on.
I have contacted the SIP Provider and they say the hangup signal is coming from the other side, but I can’t trace out anything wrong other than the phones firmware.
These systems have been running fine for some time before any upgrades and I’m certain the receptionists are answering the calls normal.
Has anyone else encountered this issue since upgrading?
