Greetings everyone, I have a problem with a Panasonic TDE 100 PBX. I connected it to the network to install proprietary IP phones using a MikroTik router.
The phones registered successfully, but I only have one-way audio.
Any ideas on how to fix the issue?
You need to create rules on Mikrotik/Firewall
Signaling ports 2427, 2727 and 9300 forward to IP adress of IPC MPR
RTP (Voice) ports 8000-12000 forward to IP adress of DSP
