I've just ported my number to 2talk and am trying the following configuration:
* One Number enabled
* Cisco SPA122 ATA using 09xxxxxxx (primary)
* Android 2talk Connect app using 09xxxxxxx-1
* iPhone 2talk Connect app using 09xxxxxxx-2
When 09xxxxxxx is called, all devices ring simultaneously, as expected.
I've since tried and failed to configure it so that only the primary rings, then the Android (delayed), and finally the iPhone (further delayed). I tried enabling these fallback numbers with hunt mode and delays in the One Number configuration section. I also tried enabling a Hunt Group with the same numbers. The devices always ring simultaneously. What am I missing?
