Question: How do I register the GXV3140 to a SIP server?
Answer:

You can register the GXV3140 to a SIP server through the web interface or the LCD menu. Before registering, please make sure that you have valid login information with a valid SIP server. If this information is not valid, the phone cannot be registered.

Log into the web configuration interface and select the corresponding Account page. If the GXV3140 is on a LAN and needs to register to a SIP server on the Internet, NAT traversal is required. Please select the NAT traversal type according to the network environment you are in. If you are unsure, please select “Auto” for NAT Traversal. To register the account, enter the Account Name (optional), SIP server, SIP User ID, Authenticate ID, Authenticate Password, Voicemail User ID (optional) and Name (optional). Press Save and restart the phone.

If the GXV3140 and the SIP server are on the same LAN, NAT traversal is not needed.

To register the phone through the phone LCD screen, select [MENU]→[Settings]→[Accounts] →[Account], and enter the required information (similar to the web interface).

Note: If the default primary IPVideoTalk account is changed and needs to be restored, please factory restore the unit. Normally an Outbound Proxy is not required. If it is needed, please enter the outbound proxy IP address or domain name.
