Easy, now. I just added another T1, and I have noticed the D-Channel dropping for a few seconds then coming right back, fortunately in the wee hours when no one's on the lines. But I have both busydetect and callprogress off, with a T400 tho not a T100. Here's some zaptel.conf: span=1,0,0,esf,b8zs span=2,0,0,esf,b8zs span=3,1,0,esf,b8zs span=4,0,0,esf,b8zs First 2 spans are channel banks, span 3 is local T1, and span 4 is long distance T1. The D-Channel only appears to drop on span 4, although I can't yet get the time to play wire/card-swap much due to the machine being in production. Both T1's are from the same switch, so I'm told, so it should be the same clock. Here's some log: Jan 9 04:22:05 WARNING[5126]: File chan_zap.c, Line 5759 (zt_pri_error): PRI: Read on 106 failed: Unknown error 500 Jan 9 04:22:05 WARNING[6151]: File chan_zap.c, Line 4708 (handle_init_event): Detected alarm on channel 73: Red Alarm Jan 9 04:22:05 WARNING[6151]: File chan_zap.c, Line 1101 (zt_disable_ec): Unable to disable echo cancellation on channel 73 Jan 9 04:22:05 WARNING[6151]: File chan_zap.c, Line 4708 (handle_init_event): Detected alarm on channel 74: Red Alarm Jan 9 04:22:05 WARNING[6151]: File chan_zap.c, Line 1101 (zt_disable_ec): Unable to disable echo cancellation on channel 74 ...last 2 lines repeated for each channel on span 4 (up to channel 95) all at the same time Jan 9 04:22:11 NOTICE[6151]: File chan_zap.c, Line 4703 (handle_init_event): Alarm cleared on channel 73 Jan 9 04:22:11 NOTICE[6151]: File chan_zap.c, Line 4703 (handle_init_event): Alarm cleared on channel 74 ...again repeated at the same time for every channel on span 4 Jan 9 04:22:11 WARNING[5126]: File chan_zap.c, Line 5759 (zt_pri_error): PRI: Read on 106 failed: Unknown error 500 Jan 9 04:22:14 VERBOSE[5126]: == D-Channel on span 4 down Jan 9 04:22:20 VERBOSE[5126]: == D-Channel on span 4 up ...and then the B-Channels start coming back up I'm trying to blame it on the mobo and the telco, but now that someone else is seeing it, maybe it's * ? It wasn't a problem when I had one T1, and span 3 doesn't seem to ever drop, so maybe it's something with the span 4 port on the T400 card ? Or is this some side-effect of the known buffering problem ? --Chris -- Chris Maj <cmaj_hat_freedomcorpse_hot_info> Pronunciation Guide: Maj == May Fingerprint: 43D6 799C F6CF F920 6623 DC85 C8A3 CFFE F0DE C146 _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
