Logic of selecting ISDN BRI channels for GSM Gateway call load balancing

Hello,

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.

Thank you.

No, router will always choose the highest free channel on a single BRI.

It would be possible, via trunk-group, when using multiple BRIs.

It can be possible on gateway it self. Got SIP GSM gateway where I can implement some logic. Not sure about your model tho.

We tried with the GSM gateway but it doesn't work. There is something written in the data sheet but there isn't documentation about it.

Now I will try to do it by prefix. For example 50% of the end users will prefix the calls with 7 and 50% with 8. The calls started with 7 will be routed to the first card and with 8 to the second.

I hoped for smarter configuration but there isn't way.

Thank you.
