[Asterisk-Users] How do you force Asterisk to use only specific codecs?

2003-07-03 Thread Chip G
Is there a way in Asterisk configuration to force the
use of specific codecs only... for example:

Never use GSM
Try G.723 if available with end point
Try G.729 if available with end point
Try G.711 if available with end point

Something like that?

Thanks!
Chip

[Asterisk-Users] How does Asterisk handle connecting two IP end points?

2003-07-03 Thread Chip G
When a connection is carried between two IP end
points, does the Asterisk server incur CPU usage to
pass the voice bearing circuit between the two end
points? Is it possible to have Asterisk setup the call
but hand off the voice traffic to be handled directly
between the two end points?

Thanks!
Chip

[Asterisk-Users] Terrible audio quality using Asterisk and X-Lite?

2003-06-27 Thread Chip G
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
