I have just upgraded my Polycom 501's from 1.6.2.0041 to 2.1.0.2708 to get the microbrowser. Almost everything is fine except when receiving calls from a BT200 (1.1.14 and earlier) the Polycom rings but when answered, drops out and the BT200 gets a busy tone. I have many PAP2T's and SPA3000's etc and they all cal call the Polycom without problem. Does anyone know what could be going on ? Thanks. -- Kevin Withnall kevin.withnall.com ILB Computing ilb.com.au PH: 02 4227 0001 Mobile: 0412 453 846 FAX: 02 4227 0081 Please consider the environment before printing this e-mail
