Fax-over-IP Configuration
This section describes how to configure MAXCS for Fax-over-IP (FoIP).
Release 7.5 supports FoIP, leveraging T-38 pass-through. (T.38 pass-through is only supported on AltiGen
SIP Trunks.)
Both voice calls and fax calls can be made through a FoIP extension; both incoming and outgoing calls on the
extension will use G.711 codec.
Fax extension-to-extension is supported; the SIP endpoints must be a supported ATA device.
Limited FoIP extension parameters are supported:
• First/Last Name, Password, Description, Department
• DID Number, Transmitted Caller ID, E911 CID
• IP Extension parameters, except Enable Fallback to Mobile Extension
• Out Call Restrictions
• Forward All Calls - forwarding target must be an FoIP extension or FoIP hunt group
• Busy Call Handling - forwarding target must be an FoIP extension or FoIP hunt group
Limitations
Sending and receiving faxes over IP service has known limitations. AltiGen, along with many other companies,
uses the T.38 industry standard for FoIP configuration. The T.38 standard contains minor variations in how it
can be implemented. Because of these variations, one provider’s FoIP handling can vary from another’s, thus
introducing the possibility of incompatibilities. As the standard continues to evolve, it is reasonable to expect
these variations to diminish over time.
If your organization typically sends frequent faxes that are lengthy multiple page documents, consider retaining
a few analog lines and traditional fax machines as a backup option.
Requirements
In order to implement FoIP, your system must meet the following requirements:
• Your system must be running MAXCS Release 7.5.
• Your SIP Service provider must be AltiGen.
• You FoIP gateway must be an AltiGen-certified ATA device. Supported devices include various
AudioCodes gateways; see the AltiGen Knowledge Base for device configuration guides.
