[VoiceOps] Call quality issue / survey

[Nathan Anderson]

Thanks for participating.  The chime is actually there on both...if you can repeat the test later from a landline, that would be swell!

Thanks,

I feel like the second one is dropping the first 2 or 3 seconds of audio. Calling from an AT&T cellphone, but I don't get the intro chime on the second recording, only the first.

It could be related to the second carriers early media handling, but I wouldn't necessarily chock it up to that.

Fun test. We just did this with about 30 different carriers; that was fun. Kept QA busy for a couple days lol.

Cheers,
Joshua

I have made two audio rips from two RTP captures I made of two phone calls through two different termination carriers to the same phone number (in this case, it happens to be to the IVR at City Hall of Fairbanks, AK).  I have temporarily allocated 2 DIDs for the purpose of this game, and depending on which one you call, you will either hear played back to you the recording of the call as it happened through one carrier, or through the other.

I am not going to tell you which one I prefer nor which carrier terminated which recording (I'm actually not 100% sure yet in the case of one of them), or even which carriers are involved, at least until after I've gotten some feedback from you all first.
