Assuming that 'clock slips' are the same thing as 'frame slips'.... Where is your primary clock? Do you have an atomic clock supplying timing to your Nortel system? Does your Nortel get it's clock from the phone company? Assuming one of these two is the case, and that both T1s are connected to the Nortel system, Asterisk should derive it's clock from the Nortel system. To do that you would want to set up Zaptel.conf span=1,1,0,esf,b8zs span=2,2,0,esf,b8zs Asterisk would then use T1 number 1 to set it's internal t1 card clock. If T1 1 was not available, then it would use T1 2. This line from your Nortel system makes me think it is using an external clock. If this is the case then you must have an atomic clock or some other 'external' clock source at your location. > CLOK EXT Don Pobanz _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
