MAKING THE FIRST CALL WITH IPVIDEOTALK SERVICE

GXV3175 offers users the ability to send and receive free lifetime video calls to other GXV3175/GXV3140 on the IPVideoTalk network. Once the GXV3175 is connected, video calls can be made using Grandstream’s configuration peer-to-peer SIP technology and IPVideoTalk service. To place the first video call, complete the following three simple steps:
1) Connect the handset, network cable and power adapter to the GXV3175 using the methods described above. After the phone boots up and obtains an IP address through DHCP, it will attempt to register to the IPVideoTalk network. When the user boots the phone for the first time, Account 1 will be registered to the IPVideoTalk server with a provisioned extension number 810xxxx.
2) If the registration is successful, the “IPVideoTalk” text on the LCD will turn green and an assigned IPVideoTalk number (810xxxx) specific to this phone will be displayed. At this point, the phone is ready for making and receiving video calls over the IPVideoTalk network.
Grandstream Networks, Inc. GXV3175 USER MANUAL Page 14 of 119 FIRMWARE VERSION 1.0.0.32 Updated : 12/2010
3) Tap on the account (See Figure 5) in the touch screen then the dial pad will show up for on-hook dialing (See Figure 6). Dial the number of any other phone registered on the IPVideoTalk network and press “Video Call” or “Audio Call” button in the dial pad. If the user has purchased more GXV3175/GXV3140 IP Multimedia phones, these phones are able to establish video calls between each other and the user will immediately experience the plug and play nature of the GXV3175. If a user has only one GXV3175, the user can choose to experience the multimedia features by dialing 0 to establish a video call with the preset extension on the server .
