Getting Started SIP Gateway Example

In this section, two 8FXS Gateways are configured to be used as SIP Gateways. The end-
point numbers are from 101 through 108 for the first Gateway and from 201 through 208 for
the second Gateway. After finishing the configuration, you can perform telephone calls
between telephones connected to a single 8FXS Gateway, or between both VCX V7111
Gateways. SIP Proxy is not used in this example, and call routing is performed using the
internal Tel to IP Routing table.
To configure the call, follow these steps:
Check connections and tools setup (TFTP, BootP, and HyperTerminal).

install the Microsoft Office 2000 Excel application.
In this example, the EXCEL utility is used:
Invoke the EXCEL utility.
On the Endpoints sheet, define local phone numbers for each 8FXS Gateway. For
the first Gateway, define local phone numbers: from 101 through 108. For the second
Gateway, define local phone numbers: from 201 through 208.
On the Phones Prefix Routing Table sheet, define routing IP addresses for each
dialed number. (This is required when a proxy is not used.)
On the SipGW sheet, define that SIP Proxy is not used.
Click the Generate SIP INI File button in the General sheet.
Check that the SipGW.ini file was generated in the folder C:\SIPgw\.
