Re: Is the NetVanta 5660 device capabale of handling analog fax service?
To the best of my knowledge the 5660 doesn't directly support analog lines. If you are using an ATA or TA900 series device behind it for analog line termination, the fax capabilities of that device would be the determining factor.
