You can enable and disable inbound faxes for users associated with a Unified Messaging (UM) mailbox policy. By default, when you enable users for UM, users can't receive fax messages until you enable inbound faxing on the UM mailbox policy and specify the URI for the partner fax server. If the URIs are configured on the UM mailbox policy but the option to allow incoming faxes is disabled on the UM dial plan or for an individual user, UM-enabled users linked to the UM mailbox policy still won't be able to receive faxes.

For more information about fax partners, see Microsoft PinPoint for Fax Partners.

For additional management tasks related to faxing, see Faxing Procedures.

What do you want to do?

Use the EAC to set the fax partner URI

  1. In the EAC, navigate to Unified Messaging > UM dial plans. In the list view, select the UM dial plan you want to modify, and then click Edit Edit Icon.

  2. On the UM dial plan page, under UM Mailbox Policies, select the policy you want to modify, and then click Edit Edit Icon.

  3. On the UM mailbox policy page > General, in the Partner fax server URI box, enter the TCP or TLS URI. For example: sip:faxserver1.contoso.com:5060;transport=tcp or sip:faxserver2.contoso.com:5061;transport=tls

    Note:
    Although the box can contain more than one fax server URI, only one will be used. If you enter two URIs, only the first will be used.
  4. Click Save to save your changes.

Use the Shell to set the fax partner URI

This example allows users who are linked with the UM mailbox policy UMDialPlan Default Policy to use TCP with port 5060 for the partner fax server faxserver1.

Copy Code 
Set-UMMailboxPolicy "UMDialPlan Default Policy" -FaxServerURI sip:faxserver1.contoso.com:5060;transport=tcp

This example allows users who are linked with the UM mailbox policy UMDialPlan Default Policy to use TLS with port 5061 for the partner fax server faxserver2.

Copy Code 
Set-UMMailboxPolicy "UMDialPlan Default Policy" -FaxServerURI sip:faxserver2.contoso.com:5061;transport=tls
