Go to the Voxtelesys Portal.

Select "APIs," then click on the "Fax Profiles" tab.

Click on the green plus (+) sign.

Fill out the following fields:

• Description: How you want to name your eFax profile
• Outbound Trunk Group: Select your outbound trunk group group from the drop down.
• Caller ID: Select your main fax number
• Event type: Select "Send an Email callback"
• Email Recipient(s): Enter the email(s) you want to receive Inbound faxes. Separate the emails with a comma and no space for more than 1.

Optional fields:

• Default: Check this box if it is your only profile on the default
• Attachment Password: Set a password if you would like your Inbound faxes to have a password to open.

This is an optional field for if you will have multiple fax numbers to assign each of them their own inbound destination.

To the right is an example of adding one:

Important Note:
Read the information below the Allowed Emails tab before adding. If you need to whitelist an entire domain please create a support ticket to have our support team do this for you. We can only assign 1 outbound caller ID to the domain/email so if you have multiple outbound fax caller IDs you will not want to whitelist a domain.

This is where you can assign a caller ID and also allows specific emails to send outgoing faxes.
