KX TDE100 ghost dials

[jpgoal]

New to the forum, so sorry if this has been asked already.

I have a KX TDE 100 that works fine until I connect the management interface to my network. Once connected eventually the phones start going on hook, or the intercom turns on and it tries to dial, or at least I hear tones. Sometimes inhouse calls are made from extensions which are not even programmed.

Can anyone offer some insites?

any sip extensions on the system.
when you say connect the management system to your network, is this connecting the system to your lan

There are about 20 extensions total.
Correct. The system connects to the LAN so it can be administered via the PBX United app. The port is forwarded through the firewall to get to the TDE 100.

You should run wireshark trace to see if someone is trying to hack your system, it can cause system to act strange
