Can you put them on a server where the devs can use wget or a browser
to download them?

The typing it takes to start a pcap of each call and email them is
less than you have typed thusfar.
Please just take the captures and send them to us to examine. That's
all. If you have a real issue we would like to address it.

If it wasn't meant as a troll I personally, publically, and directly
apologize to you...

What I see all the time is people want everything for free and then think
its the developers responsibility to give away free tech support on this
software which is free in the first place.

Tony and his crew work on FreeSWITCH as much to feed their families as they
do to have an open platform that anyone can use

I re-tested calls to VM replacing some of FS prompts with * ones, and it
appears that * sounds were recorded with a better quality/higher volume,
so FS itself has nothing to do with that. That's solved. Smile
I am going to double check all the equipment we used for tests, like
headphones, telephone sets, cables since I am almost convinced that
there's nothing in FS which can produce effects I observe.
I will post back if I find anything wrong, appreciate everybody's help
with this.

For what it's worth, using Asterisk recordings, I found FS to be better
than when played on an Asterisk system.

I came to the same conclusion early on that the included prompts with FS
were of a relatively poor nature. Not volunteering to record new ones,
but they do let the product down, as they lead to discussions as below.

There is also another side to make mimd to: the Asterisk sounds you
hear more often (the demo ones) are very long ones.

The ones of the FS demo are very very short (many times just one word)
and concatenated with the insertion of sleeps.

That is probably someway altering the equation between user experiences

Back in November, Brian ( BKW ) was raising money to get new sounds recorded ...
intending to have them for the 1.0.2 release..

I wonder if they made it in, or if they are still coming ...

Release 1.0.7 of the sound files was made available soon thereafter, which I
understand includes the new material that was recorded. I might be wrong,
though.

There's a long history of people in A/B listening tests reporting louder
as sounding
better on the same source material - even if the additional volume isn't
detectable
as such.

Which, I guess, explains my 25 years of going to Motorhead gigs.

Yes, you are right Smile And therefor a lot of (nearly all of) European
TelCo operator (TDM, not VoIP) normalize their messages to -3 dB instead
of -6 dB.
And one of them (yes, you guess it right, it is Telefonica O2 Smile
normalize recordings to 0 dB. And it is VERY loud Smile

Maybe the sox script brian uses to downsample the files has a problem.
What if you download the 48k package (original) and listen to that?
