| The issue with using copper trunks and IP is an impedance mismatch the jitter buffer normally will not help when the issue involves copper trunks. Make sure that you have NLP set to on and that you have the correct Pad settings for the trunk route that your copper trunks are in.
Check Command 0A22> Interface #> 0
Then you could adjust the pad for the trunk route you are working on.
3519 > Trunk Route for POTS Lines > 6 3db transmit/receive
post back and let me know if it helps |
