Re: [asterisk-users] BT ISDN-30 Call Failures
Any probs with the circuits? Try and upgrade?

[asterisk-users] BT ISDN-30 Call Failures
I'm seeing both inbound and outgoing call failures on our ISDN-30 lines that only seem to go away when I do a zap restart or in extremis restart Asterisk (1.4.25 with a Digium TE205P and zaptel 1.4.12.1). If I don't restart zapata or Asterisk the problem rapidly get worse :-( The lines are from BT with LCR from CableWireless (I've tried using the LCR bypass code and it doesn't make any difference). The outbound symptoms are that the number appears to go out on the ISDN but the caller hears nothing and the callee's phone doesn't ring (example below with ISDN debug on). The incoming problem is that the callee's phone rings for a couple of seconds and then the call gets cutoff (again example enclosed) or sometimes doesn't appear at all in the Asterisk logs and the callee gets a busy tone (no the system hasn't used all of the channels at this point :-).
