[USR-TC] Mac's DSP's and PRI's

Gentlemen, We have run into a problem here. Recently we upgraded to the newer code on our DSP's. Code 3.5.105 And at the same time (or nearly there) we changed from CT1's to PRI's Almost everything is work ing quite well. No big change in the normal amount of failed calls and no new modem types that will not connect. Except a handfull of Mac's -- Still collecting info but it seems that the iMac's are the problems. Tradionally we have never had as much luck with our Mac customers as we have had with our PC customers. And certainly the competition, who's still running (I think) PM gear is the preferred Mac guy around here. Anyone had this same problem? Is there a fix for this? Terry
