Hi, We've been using zaphfc single ISDN cards as cheap Zaptel timing sources for our Asterisk boxes for a long time, and in the asterisk 1.0.x series, had zero problems doing so.
I now have some boxes with Zaptel 1.2.x (with a mixture of 1.0.x asterisk and 1.2.x asterisk), and this setup no-longer seems stable - By plugging or unplugging the ISDN cable, and sometimes just randomly the card will start spewing buffer over/underring errors. I already knew about the florz patch, and I have to say that this makes a HUGE difference - It seems to stabilise things to the point where it will run for a week, but does still go mouldy after a while with a constant stream of: Nov 16 15:54:01 pabx kernel: zaphfc[0]: b channel buffer overflow: 854, 854 Nov 16 15:54:05 pabx kernel: zaphfc[0]: b channel buffer underrun: 0, 0 Nov 16 15:54:05 pabx kernel: zaphfc[0]: b channel buffer overflow: 446, 446 Nov 16 15:54:06 pabx kernel: zaphfc[0]: b channel buffer overflow: 855, 855 Nov 16 15:54:06 pabx kernel: zaphfc[0]: b channel buffer underrun: 0, 0 This leaves the box sufficiently ill that a power-down is the only way to recover. Can anyone offer any pointers? Is there an alternative but equally cheap hardware Zaptel timing source out there perhaps? Preferably one which offers a single ISDN2e port :) P.S. Restarting Asterisk and/or Zaptel every night is not a good answer except from a Windows administrator :) Thanks Steve _______________________________________________ --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
