Anyone know of best way to test for PRI troubles? Any way to STAT D-channel for issues with carrier as with old Nortel switches? I can do a 'PRI show channels' and a 'PRI show span 1' in the asterisk CLI tab under tools but that doesn't tell me much. I have a PRI that occasionally drops calls and sometimes stops working inbound and out although the UCX sees it as up and active and indicates no PRI D-channel errors in the 'full' log and of course the carrier sees no trouble as well. I know I can set up PRI debug but because it's so sporadic my log files will overflow with tons of data. Is there any other commands or tools to test a PRI?
