We are having some issues with "no ch available" on a specific trunk. Doesn't happen all the time. Our provider (Cox) says the calls are not reaching their system when this happens. The attempts when no channel available happens never show up in the SMDR.

I've found the System Call Log (6.7.1) in DM but don't exactly understand the format. I'm hoping the log can help track down the error(s).

Is there any documentation regarding the layout of this file?
Is there a way to capture this file similar to the SMDR data?

Thanks in advance!
