I need a different zap channel selection behaviour than is currently provided by either g,G,r,R.
I need a true sequential selection of outgoing ZAP channel so that each new outbound call gets the next highest available channel.
I basically need an even distribution of calls across the channels.
Why do I need this?
In the UK, British Telecom (BT) offer a package called ONE Plan inclusive that allows you to pay ~£14 a month per channel to get a bunch of inclusive minutes again per channel. So when you have 20 channels and the utilisation is 60-70% then you need to use all of the channels to make best use of the inclusive minutes. The current ZAP options don’t make this easy to achieve.
So before I start hacking the chan_zap.so up. Has anyone any suggestions or thoughts about this?
