I'm guessing the answer is "can't get there from here" unless it's modem calls. I'm interested in the calling number info that is coming in on the PRI. I can view a modem call and get the calling number info, but not on ISDN, which is all I'm running. Trying performance monitor on the T1, nothing there like it. Using a Netserver with das Munich daughterboard und dual T1, works really quite well. Might be a mighty cheap way for some of you to do ISDN only traffic for dedicated customers. You can do the Dual PRI& Netserver in same chassis as with a HiperARC & DSP's. Neat. I'm also wondering whether I can get via radius accounting that "calling number" from a Netserver/or is it NMC??? Anybody be able to shed some light? SMT Scott M. Trautman 800-482-4638 Global Dialog Internet 608-240-4638,4637fax 2810 Crossroads, STE LL2 scott@gdinet.com Madison WI 53718 http://www.gdinet.com
