Polygator GSM Card with asterisk with multi ring groups

Hello,

Can someone please help me configuring my PolyGator GSM card?

Based on the manufacturer, I’ve managed to configure one SIM channel to ring on specific ring group extension.

What I need to do is that I want to have each of the four GSM channels to ring a separate extension.

When I configure the second SIM card, it keeps ringing on the first ring group.

Can some one please help?

The commands I used on the asterisk -r CLI:

polygator channel gsm gsm-01 set incoming spec polygator channel gsm gsm-01 set context from-pstn polygator channel gsm gsm-01 set extension 601

Looking forward for any help.

All the best,
