ATA FAXING PROBLEMS THROUGH PRI GATEWAY

Has anyone got faxing to work with the ATA186 through a PRI gateway? It keeps failing on the 3rd or 4th page? I have upgraded it to ver 2.14 and the 3660 router is running 12.2.8T3. Faxing across LAN/WAN works fine with no problem. All pages send and receive without a problem no matter how many.

Re: ATA FAXING PROBLEMS THROUGH PRI GATEWAY

A couple things come to mind...

The ATA-186 only supports fax speeds up to 9600 baud. Also the ATA-186 only supports fax pass-through; fax relay is not supported, something to do with DSP limitations. In what mode do you have the ATA-186 running; SCCP, H323, MGCP? I've had the best luck with faxing by configuring the ATA in H323 mode.

You can check the ATA-186 FAQ for more info.
