Hi guys, I’m back to investigate ringback issues with Groundwire (Android), this time: the problem is the ringback tone generated is 440Hz: 2 seconds on, 4 seconds off and it is completely missing the 480Hz tone. It makes it hard to hear and distinguish from other line signals and it’s driving me crazy.
I spoke with a CS agent at VoIP.ms, we did a quick test and determined the the culprit is indeed the Groundwire app. I also did my own test with my HT802V2 and there was no issue with its ringback.
Anybody have any idea? I tried changing codec to G711.U but behaviour was the same. This seems to be a really difficult issue to search for online as well.
I have also opened a ticket with Acrobits to look into this, and I will be posting the findings here later when I hear back.
Thanks guys, appreciate any insight!!
