SPA8000 can only do incoming calls

The SPA8000 is an 8 FXS Port device that will allow you to configure an 8 line analog system for inbound calls. The SPA will convert your analog line into digital voip. This is useful if you need to setup an inbound system.

Note the SPA8000 can not do any outbound calls.

Some of the settings within the administration page will need to be changed.

Those settings are:

// PSTN Line Tab: key params
Line Enable = yes
SIP Port = 5061
SIP Remote-Party-ID = off
Make Call Without Reg = on
Ans Call Without Reg = on
Preferred Codec = G711u
