Please notice earlier it was working absolutely perfect no distortion was there.

Hi all i got it right
just check the application codec like if your application softsphone support codecs like ulaw ,alaw ,g729 .
then do the following in sip .conf file

[code][general]

disallow=all
allow=ulaw
allow=alaw[/code]
