I have an Asterisk PBX server. I want to use XLite to make a call
from a non-local computer (outside local lan). I test the calling with a Playback(hello-world).
I can hear the message, but the quality of sound is very poor. A lot of background noise and the the message is robotic.
A ping to the pbx server takes about 50-60ms.
I tried to enable in sip.conf only some codecs (not all), but no improvement was done.
Is there anything can be done for the improvement of sound quality, in asterisk and XLite?
