Trunk Configuration - Grandstream Networks GXE502X User Manual

3. Trunk Configuration

PSTN trunks, SIP trunks and SIP-based PSTN trunks (extended via Grandstream FXO Gateways)
can all be configured on the GXE502X in the Trunk/Phone Lines menu.
The FXO and FXS port/line electric specification parameters and settings can be configured in this
area as well. All of these will allow users of the GXE502X to make calls anywhere through multiple
trunk types.
- Internal PSTN Trunk Line Configuration (via FXO ports)
The Internal PSTN Trunk Line Configuration page lets your configure the FXO ports on the back of
the GXE502X to make and receive calls to and from the PSTN.
Compatibility with different PSTN lines can be achieved by adjusting the related parameters on the
Internal PSTN Trunk Line Parameter page. The default settings should function in most cases.
Correct technical data must be obtained from local Telco carriers and implemented on the GXE502X
before the lines will function. This data depends on the regional PSTN line characteristics.
