I have an Epygi Quadro 4L (Firmware 5.3.21) with 4 analog lines for dial tone. I am using 5 Snom 820 phones (Firmware 8.7.3.15).
Calls ring in to a virtual extension that has "many extensions ringing" activated. All phones ring on incoming calls.
When a call is answered, the line seizure is not immediate, and you can still hear a partial ring in the handset before being connected to the calling party.
Why is the Epygi not showing immediate line seizure to the PSTN?
The lines were working fine with the previous phone system.
