3rd Party Faxing

I have seen the post on faxing and the abilities to recieve faxes Using the

Program on

I would like to know if Unity UM is required?

I only have Unity VM but would like to implement a IP faxing Solution.

Another question is.

What other 3rd Party fax vendors does Cisco approve for Intergration with Call Manger and Unity?

Re: 3rd Party Faxing

No, UM is not required for that solution to work... you can get and retrieve faxes so long as you have fax mail options for users on your system (which don't require UM).

The official list of fax servers we've tested with includes:

Captaris RightFax Version 6 or higher

Esker FaxGate Version 7 or higher

FAXCOM for Exchange Version 6.19 or higher

Fenestrae FAXination Version 4 or higher

Interstar LighteningFax Version 5.5 or higher

Interstar XMedius

Omtool Fax Sr. Version 3 or higher

Optus FACSys Version 4.5 or higher


You can check out the 3rd party fax administration tool here:

this allows you to configure the registry for any of the above fax servers easily - you have to run this on 4.0(1) or later, for 3.x it's optional but reccomended.

Re: 3rd Party Faxing

Thank You for the Very Informative response.

How would I go about upgrading Unity to Have Fax mail Options enabled without having to go with the Full Blown UM upgrade.

We are currently running 3.1.1 and the License Count show 0 For Fax Mail Users.

Thanks Again.
