[c-nsp] QOS Problem - T1 Interface

[Paul Stewart]

Hi folks...

 

I need a second set of eyes here...;)  We have a customer fed off T1 to an
Adtran router that is having problems with their voice quality... they also
share this as their Internet connection.

 

A ticket is open with Adtran to confirm their QOS settings but I'm hoping to
clarify if below is correct? ;)  

 

At the moment I'm capturing this, they have no active voice calls....
