Using an Axtan IPCallBox with VoIP Unlimited

Axtan has performed interoperability testing with the VoIP Unlimited SIP breakout service using the IPCallBox products to ensure easy installation for system integrators.

Please download the application note on how to build IPCallBox configuration files to use with VoIP Unlimited. Note that it is important to start any configuration using one of the configuration templates supplied in this pack otherwise you will not be able to use VoIP Unlimited's STUN server when behind NAT.

The firmware on our box is upgradable so please ensure that you are using a minimum of 1.2.73 which was tested with VoIP Unlimited. This can be downloaded from the secure download area.

T.38 fax is not supported by VoIP Unlimited at this time.
