Hi,
So I've been working on this problem for several months to no avail. My system is on 5.2.1.
We have 15 sites (all in the same area code, on the same CM) and all of them are experiencing fax problems at every site. The problems are intermittent, but from what I can tell, they have the highest chance of failing when the other party is using a fax server like Ritefax. Both sending and receiving, partial pages and incomplete faxes are occurring, along with Comm. Errors. These usually go over a PRI, though I do have analog trunks that I've sent the faxes over to troubleshoot with the same result. If I plug directly in to the analog modem and bypass our system entirely, I have no problems. That leads me to believe that the problem is in fact on my side. They were having fax issues before I took this position, so I have no data concerning changes made before I was here.
Here are some things I've tried that didn't seem to change much:
Turned off any and all ECM
Tried Setting ip-codec-set p.1 "Audio Codec" to G.711MU, G.711A, G. 729
Tried setting ip-codec-set p.2 "Mode" to pass-through, relay, and t.38
Called PRI provider and asked what is recommended Mode/Codec, and set accordingly
Discovered Primary Sync Source was defunct, and set a new sync source (I'm wondering If I need to dig into this further)
Tried multiple brands/types of fax machines
Changed Transmission Speed of Fax machines
Changed XOIP endpoint type in station to AUTO (This was a wild guess)
And a few other things I'm sure I'm forgetting. . .
Please, if you have any knowledge to impart, don't feel like you're imposing. I'm fairly new to phone systems in general.
Thanks,
Thurman
