Don't know if it is g.107 but it has to be something similar if it
isn't. I'm personally more interessted in the network statitics.

The professional way is to do a series of test calls, play a reference
file and record the audio at the incoming side. You then use both files
to calculate a MOS score. This method is used by telco's to do quality

Hi,
How do you typically test voice quality in Asterisk? For example if you like to
do load testing, or monitor voice quality and get notified if certain calls had
bad quality for proactive maintenance?
Thank you!

Normally, there are 10 concurrent calls in peak. You are right that
usage g729 is due to bandwidth consideration.

Hi all,
I wonder who has the same voice quality problem as what we have.
Below is our configuration.
Company --- asterisk 1.4.22 (g729) --- CISCO --- T1 --- customer
Sometimes, customers told me that they heard our voice not very clear,
like a call from far far away. I heard the recording is ok

Or that. Certainly, my own experiences with IAX2 would support this

Being new to Asterisk, I have set up a little test rig at home.
Asterisk itself is the Debian Etch package, running on a Celeron 1.7G

I have two clients on a 100Mb LAN, a Windows XP machine with an Athlon

Aastra is a great phone for sound quality and other features. I didn't have

Scott,
I've used the phone for 9 months. It's a truly outstanding phone. The cordless
handset sounds great. It is limited to two ongoing calls at one time, but that
has not been an issue for me.
The range on the cordless is comparable to the Panasonic KX-TG4000 KSU that I
used to use and a Pan

able to find another unit that has this same feature.

Looking for feedback on the cordless phones with the Aastra 480i CT handset. Is
voice quality comparable to standard consumer residential 2.4GHz cordless

How about handset and speakerphone quality for the main phone?

Hi ,
Does anyone encounter this problem ? We have installed Asterisk at Site
A and have 128k Frame Relay over to Site B.
We are using Zyxel 2 port FXS at Site B and Linksys PAP2-NA at Site A.
We are using Ulaw at Site A and G729 at Site B.

I would use g.729, and if this is an issue, GSM.
Setup trunking between both IAX peers so that you can save a lot of
bandwidth.

What's your end device? if it's a voip device (eg SIP phone or a soft
phone) then you shouldn't need a jitter buffer.
Also, you don't need bandwidth=low if you specify the codecs (the
disallow=all will override the bandwidth=low) and maxjitterbuffer is the
