Asterisk Users, I am running a Debian "Etch" system with Asterisk 1.4.11 with a TDM03B card. Once in awhile, I get this error on the Asterisk, which causes my channels to be busy/congested, leaving me with just one channel to recieve and make calls: NOTICE[31454]: chan_zap.c:6367 ss_thread: Got event 17 (Polarity Reversal)... WARNING[31454]: chan_zap.c:6499 ss_thread: CallerID returned with error on channel 'Zap/3-1' What could be causing this issue? Any would input would be greatly appreciated. Thanks In Advance, John _________________________________________________________________ Use video conversation to talk face-to-face with Windows Live Messenger. http://www.windowslive.com/messenger/connect_your_way.html?ocid=TXT_TAGLM_WL_Refresh_messenger_video_042008 -------------- next part -------------- An HTML attachment was scrubbed...
