INTRODUCTION
NXGW-XET1 Gateway is an open-source Asterisk-based VoIP Gateway. It is a converged media gateway prod-
uct. This kind of gateway connects traditional telephone systems to IP networks and integrates VoIP PBX with
the PSTN seamlessly. With a friendly GUI, users may easily set up their customized Gateway. Also, secondary
development can be completed through AMI (Asterisk Management Interface).
It is developed with a wide selection of codecs and signaling protocol, including G.711A, G.711U, G.729, G.722,
G.723 and GSM. It supports PRI/SS7/R2 protocol. The NXGW-XET1 Gateway has good processing ability and
stability. The NXGW-XET1 gateway is 100% compatible with Asterisk, Elastix, 3CX, FreeSWITCH SIP server and
VOS VoIP operating platform.

PRI Dial Plan for Dialed
Number
PRI Dialplan: The ISDN-level Type of Number (TON) or numbering plan, used
for the dialed number. Leaving this as ‘unknown’ (the default) works for
most cases. In some very unusual circumstances, you may need to set this
to; ’dynamic’ or ‘redundant’.
PRI Dial Plan for Dialing
Number
PRI Local Dialplan: Only RARELY used for PRI (sets the calling number’s
numbering plan). In North America, the typical use is sending the 10 digits;
caller ID number and setting the prilocaldialplan to ‘national’ (the default).
Only VERY rarely will you need to change this.

ty (NSF) Messages
Some switches (AT&T especially) require network specific facility IE.
Supported values are currently ‘none’, ’sdn’, ’megacom’,’ tollfreemgacom’,’
account’.
