There isn't any compression going on, I've verified that.
They've replaced the fax machine that has the most problems but it also happens with others.
Call Q logs show everything looking just fine - no packet loss and almost no jitter.
I was about to send a tech out to replace a DSP but then the customer called and said it's working much better now. (
?)
So I haven't been able to nail it.
As for %, I was trying to send a 10 page fax and it was failing almost 100%. Then it's ok. Still leaning toward a bad DSP.
