If they are only happening occasionally, it may be a marginal, but mostly-OK signal on the wire. Do you also get occasional poor-quality audio on calls? The issue will happen more when a call is being setup, or is progressing because there are more frames being exchanged when a call is in progress. audio quality seems to be fine ( e.g. had no complaints about that) I have also seen a bad component or dry solder on a voice card cause this, and even a badly made ISDN cable can be part of the problem. If none of that helps, I would ask the telco to put a trace on the line. would these FCS errors cause the system to become unresponsive leading to Channel 0/1, span 1 got hangup, cause 18 after a period of working fine, or is this an unrelated issue? Hope that helps, Steve -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

A while after a call is made? A while after a call is ended? Maybe the provider intentionally sets layer 1 down (to save power)?

If they are only happening occasionally, it may be a marginal, but mostly-OK signal on the wire. Do you also get occasional poor-quality audio on calls? The issue will happen more when a call is being setup, or is progressing because there are more frames being exchanged when a call is in progress. I have also seen a bad component or dry solder on a voice card cause this, and even a badly made ISDN cable can be part of the problem. If none of that helps, I would ask the telco to put a trace on the line. Hope that helps, Steve -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
