I am using CallManager 3.2(2c) with 6608 gateways supporting PRI lines to the PSTN. Certain incoming faxes seemed to be "squished." That is, the entire page of the incoming fax is present - and even readable - but when it comes out of the fax machine one or two portions of it (a few lines, for example) will be condensed, or squished into a smaller than normal space.
This problem only seems to happen with certain businesses that are sending in faxes - the majority of businesses that send in faxes are fine 100% of the time. The businesses that do experience the problem when they send in faxes only see the issue 10-30% of the time - even for them the faxes work correctly the majority of the time. The businesses that send the problematic faxes always seem to be long distance - any local faxes always seem to work correctly.
We have placed our fax machines on both 6624 ports as well as VG248 ports and the problem is the same, so that doesn't seem to be the issue...
I have Fax Relay enabled on the PRI's - could this be the issue?
command is enabled it may result in condensed or squished output. This is happening due to the error in the PSTN line. ECM has a low tolerance (approximately 2 percent) for jitter and packet loss. Incomplete output on the terminating fax is a symptom of failures due to packet loss.
You can remove this command and check for a trial basis for a week or so and check the faxes transmitted.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
