User manual GRANDSTREAM GXW-400X BROCHURE

[. . . ] This scenario allows an organization with a remote location to access the local FXO trunks (Traditional PBX trunks or PSTN lines) through the IP network. [. . . ] With the help of the IP infrastructure and Grandstream GXW-400X-400X FXO and FXS Series, the remote users in Boston are able to make, as well as receive calls from Denver as if they were at the same location. NOTE: Please upgrade the firmware of the GXW-400X-400X4004 to 1. 0. 0. 39 version or higher (point the device to 168. 75. 215. 189 OR by downloading the firmware from www. grandstream. com and upgrading locally using TFTP or HTTP) and upgrade the firmware of the GXW-400X-400X410x to 1. 0. 0. 53 version or higher (available at www. grandstream. com/). Grandstream Networks Peer ­ Peer Gateways (w/o SIP Server) Page 1 of 3 CONFIGURATION OF THE GXW-400X-400X410X & GXW-400X-400X400X SCENARIO Configure the following settings for each of the devices using the Grandstream Web Configuration pages for each device. GXW-400X-400X400x Profile 1 · SIP Server - Set to IP Address of GXW-400X-400X410x · SIP Registration - No · Outgoing Call without Registration - Yes · NAT traversal ­ No Advanced Settings · STUN Server - Blank FXO lines · Wait for Dial Tone - Y or N (whichever suits your FXO lines) · Stage Method - 1 · Off-hook Auto Dial 444 @ch1-8:p1; ch1-8:5060++ Channels · Channel - 1 · SIP User ID - 5060 · Profile ID - Profile 1 · Local SIP Listen port - 5060++ Profile 1 · SIP Server - Set it to IP Address of GXW-400X-400X400x · SIP Registration - No · NAT traversal - No GXW-400X-400X410x Advanced Settings · STUN Server - Blank · Use Random Port - No NOTE: In order for this setup to work, it is extremely important that both gateways (GXW-400X-400X410x and GXW-400X-400X400x) are located on the same LAN OR Public Static IPs. In short, the GXW-400X-400Xs should be able to locate each other. Grandstream Networks Peer ­ Peer Gateways (w/o SIP Server) Page 2 of 3 ONE TO ONE MAPPING BETWEEN FXS PORT AND FXO PORTS If your setup requires that FXS port `x' user be able to access only FXO port `x' for outbound calls, use this setting under Channels Webpage on the GXW-400X-400X410x. By default the value is 99. This setting allows you the power to send an outbound call to a specific FXO line. For example: if you dial (617)123-4567 from your phone (which is connected to port 5), the number is appended with the appropriate dial plan (the actual dialed number will be 9956171234567). On the GXW-400X-400X4108 gateway (with this configuration), it will route the call to port 5 and strip off 995 and send the call over the PSTN network. Important Note: This pair of GXW-400X-400Xs should be configured with the one-stage dialing method. For example: Bob is in the Boston office (GXW-400X-400X400x). [. . . ] He needs to make an outbound call to Alice who lives in Denver with phone number XXX-566-9300. [. . . ]
