Squelch Noise on T1s

[worldwidedialtone]

Succession 1000 (61C) with 3 T1s (DTI). When cell phone incoming to switch get a squelching type noise. Checked different channels on all 3 T1s. Not all cell calls get this but the majority do on at least 4 different providers to include cell calls from overseas. Land line phones are clear as a bell. Any help is greatly appreciated. I think problem lies with the T1 provider but want to run all proabilities to ground to be sure. Thanks for any help suggestions.

the switch does not handle cell calls with any unique padding.. if you drop the gain on those trunks then your tdm calls are going to be down as well. look into the PCML and PDCA prompts on the trunks.. i've never needed to move those from default but you may want to look up the possible responses on those
