I already create my own dialplan and it's work fine. But if I reboot gateway every time all contexts in extra-channels.conf reset to gsm-1, gsm-2 and so on.
So my question - how I can change it for ever?
Sorry for it!The extra-channels is can't save when you reboot the gateway temporary!
We will think about your needs,and try to discuss it if we can add more function for it,so that you can change more file of Gateway!
