We've seen some noise issues on calls on our CUCM.
We have 3 PRI/T1 with our service provide Paetec. And 2 PRI and 1 T1 set up between our Rolm 9751 and CUCM.
All PRI/T1 have high numbers of Total Rx RPT lost pkts (over 4 billions each) when looking at device status. Occasionally I can catch a Total Rx RPT lost pkts on specific ports when looking at the PORT status, but mostly these run clean. As usage increases on a PRI, the rate of lost pkts increases too.
1. Is there a way to clear the device Total RX RPT lost pkts counts?
2. Is there a correlation between the Device Total RX RPT lost pkts and the noisy calls we're hearing?
3. Where do I look to resolve this.
I do not see errors on the Rolm 9751 side of the PRI's.
