asterisk users - Jun 2003 - Terrible audio quality using Asterisk and X-Lite?

Greetings! I have made great progress thanks to this
group. My Asterisk seems to be working for the most
part. I am using the following equipment/software:

* HP Vectra VL - Pentium Pro CPU - 256MB RAM
* Redhat Linux 8 - Loaded straight from distro CDs as
Developer Workstation - latest updates from RHN
* Asterisk (latest as of two weeks ago when I used CVS
checkout)
* X-Lite SIP Client on a Windows 2000 PC
* 10 Base-T network between the PC and the Asterisk
server
* The Win 2000 PC is acting as a router to the
Internet. It has a 10/100 NIC connected back to
Asterisk and a wireless NIC to the Internet.

I have configured using Andy's quick start and the
Asterisk manual as guides. I have setup a single
extension with voicemail. When I call, the generic
voicemail greeting answers and allows me to leave a
message. I receive an e-mail with the message
attached. However, the quality of the recording is
terrible. I also notice that the quality of the audio
during the voicemail greeting is intermittently great
and sometimes choppy/missed completely.

Are there any settings that I can tinker with to
enhance the VoIP quality in this configuration?

Thanks!
Chip

1)  Start up in run level 3, not 5 (i.e. /etc/inittab).
2)  Turn off frame buffer mode in /etc/lilo.conf, rerun lilo, and
reboot.

Hi,

Check with another software phone to see if the quality is the same.
I have run Asterisk even with GUI installed and started on a Celeron/300MHz
with 128MB of RAM with a couple of connections and it works fine for me.

Best regards,
Dan

Is the sound "choppy"??

If it is you are using the GSM codec... disable it and use G.711 (ulaw or alaw)
and the quality should be fine.. the reason is that MS GSM is not the same as
Linux GSM.. At least thats what I have been told..

Later..
