I am reaching the same level of frustration.
I have tried to find the source of the problems.
We have IAX2 to our VoIP provider and SIP phones attached to the
Asterisk - No analogue.
We have a very lightly loaded 60 Mbs cable link to the Internet that
tests pretty close to that most of the time.
I have not found any good tools to track down the causes of poor voice
quality.
In my case, I have good incoming quality and terrible quality going out.
That is, I can hear people perfectly well but they complain that my
voice drops out and is garbled regardless of who places the call.
As a result, I use Skype for all of my calls and if someone calls me, I
call them back on Skype if they have any problems.
I don't understand why Skype works so well and Asterisk works so poorly
on the same environment.
Googling "Asterisk poor audio quality" return several hundred thousand
references

All,
The users in our organization are well, quite frankly, sick of phone
service that is being provided. The choppy phone calls, and drop outs
are detrimental to our sales force.
I've tried about everything I can think of.
Moved the asterisk server from VM machine to dedicated machine
More than enough bandwidth
Setting 802.1p = 7
Set Dedicated voice traffic 35% of bandwidth.
Not sure what option would be the best
Put analog lines in the conference room to avoid the dropouts -
leave the sip lines in place for day to day use
Hire a consultant
Ditch the system and buy a pre-packaged system - RingCentral or
some such.
There are no local asterisk professionals who can help, and we are a
little leery of opening up our system to outside consultants.
Anyone else face the above, and finally abandoned Asterisk for a
commercial system?
We have 167 users.
I use Grandstream GXP 2100 on the desktop and Polycom ip6000 for the
conference rooms.
Suggestions welcome.
Best
Eddie
