Hi, 

I have downgraded the dahdi and libpri version to dahdi-2.3.0 and libpri
to 1.4.10 and did not had a disconnection as of now.

However i am facing one issue since a long time on asterisk cli and
whenever these error comes we dont get the audio at all and instead of same
its a complete silence call.

Please find the mentioned error below

Whenever these error comes like Hang up on bad channel or moving call from
X channel to Y then only we start getting silent calls else till the time
there are no errors things works pretty smooth.

Kindly suggests something on same so that this can be resolved.
