I have 2N ISDN LITE GSM Gateway. Two sim cards with some free minutes. I want to load balance between both cards. There is a thick that on the GSM GW that says 1 SIM on 1 B-chan, 2 SIM on 2 B-chan. I'm wondering is it possible to configure logic of selecting ISDN BRI channels for example longest idle.
Any other advices will be greatly appreciated.
