Using the Sipura SPA 3000 as a SIP/PSTN
gateway with PBXware
The Sipura SPA 3000 is a small and inexpensive ATA and SIP/PSTN gateway. With careful
configuration, it may be used in conjunction with PBXware in place of the Digium Zaptel
interface cards. This can be of particular advantage in some implementations since the Digium
single-port X100P FXO cards for Asterisk cannot be used, for example, in the UK due to
impedance mismatch, and the new TDM400P base price is more than double the cost of the
Sipura unit even before adding the required FXO or FXS modules.
The only disadvantage is that for PBXware licensing, each Sipura SPA 3000 counts against the
licensed number of VOIP trunks for the version of PBXware.
This how-to guide gives simple instructions on how to setup PBXware and the Sipura SPA 3000
to work together. You must use a fixed IP address with the Sipura SPA 3000 to work correctly
because of limitations of either PBXware or the Sipura SPA 3000 having mutually exclusive
authentication entities.
