208-301-5083<tel:208-301-5083>: Good quality. Sounds like a waveform codec.
208-301-5084<tel:208-301-5084>: Mostly unacceptable quality. Sounds like a
vocoder codec. Anyone that puts music at the start of an audio stream these
days is simply begging for trouble. No telling when your path is going to get
xcoded down by someone in the (probably ever-changing) path.

Test DID #1 208-301-5083<tel:208-301-5083> is much preferable in my opinion.
#2 has a loud click like Gabe pointed out and it ramps the volume up from
nearly zero to an acceptable level after a few seconds. #1 sets up faster and
immediately achieves the same level. That was fun. Thanks

Hey gang,
Let's play a game. 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.
Whoever wants to participate, please place calls to both numbers (do it either
from a landline or a G.711u VoIP session, please), and tell me which version of
the recording you prefer, why you prefer it, and if you had to put it into
words (which you do), how you would describe the difference between the two
recordings. 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.
Basically, I'm trying to find out if I'm crazy, or if there really is a
difference between the two recordings in terms of audio quality. I say there
is a stark difference. I've had others tell me they can't hear it. Maybe I
have "golden ears". :-P
Here are the two phone numbers to call:
208-301-5083<tel:208-301-5083>
208-301-5084<tel:208-301-5084>
Alternatively, for those of you would like copies of the actual audio files to
listen to, I can provide those upon request; just contact me off-list.
Thanks,

This was my experience as well. 5083 is better.

Calls placed from XO eSIP and AT&T cell, exact same results:
> 208-301-5083
:00 No ringback
:01.5 Music starts
:03 Silence and then woman speaking on the IVR. Consistent volume
> 208-301-5084
:00 No ringback
:07 Loud click
:10 Her voice is very weak and fades in (and is somewhat choppy)
:12 Normal from that point forward
208-301-5083 is far and away better. Sounds better, starts quicker, no
awkward silence.
What do I win for playing?
Best,
Gabe
