Any way to increase volume on one of our PRIs?

In our call center, we use multiple carriers on inbound calls for redundancy. Calls are routed equally from each of our toll-free numbers to one of these three carriers.

We have received numerous reports of lower-than-usual volume on certain inbound calls and have determined that "Carrier X" is the culprit. We filed a trouble ticket but they claim there is no padding being used and that everything seems OK.

Since "Carrier X" is not known for exceptional customer service or knowledgeable techs, I want to take them out of the picture completely. Thus, I am curious if there is any way for us to increase volume levels on this trunk group from within the Definity. We'd like to ramp it up a little at a time until the reports of low volume go away, or until our testing shows equal volume between "Carrier X" and carriers "Y" and "Z".

Thanks!

I should probably clarify that there are 3 PRIs in this trunk group. We'd like to increase volume on the entire trunk group itself, not necesarily each PRI (which I don't think is possible anyway).

Thanks.
