PBX is connected solely to ANALOG LINES
Problem occurs on:
- IP (digital) extensions
- Analog lines FXO1 and FXO2
- Also occurs with GXW4108 analog lines
- All lines come from service provider modems
Problem DOES NOT occurs on:
- Analog extensions (FXS ports)
I am new to GRANDSTREAM and IP telephony and don’t know if there is some programming involved in this issue.
