Hello everyone,
I need some help understanding what is going on.
This is a remote phone.
Extension number = 6406
Phone LAN IP = 192.168.10.101 (Subnet 192.168.10.0/24)
The phone is behind a TP Link router. There’s no ports forwarded etc.
The PBX is at another location behind a SonicWall.
The phone was provisioned and is registered over WAN (locked down).
No issued until yesterday.
Yesterday, the phone got a call from 6406 (it’s own extension) at 3:40 AM, tried answering, call got disconnected. Checked CDR, no details at all. I brushed it off…
Today at 5:42 AM same thing happened, answered, but this time the phone froze, couldn’t hangup, had to unplug the power…
I looked again in CDR and in Asterisk logs, Zero information there.
So I downloaded the System Log File from the actual phone. and I see the following:

SDP IP 192.168.1.83 – What is that IP address?
Can anyone explain what is going on?
Thanks
