Grandstream GXV3175v2 - How to set it up with a 2N IP Intercom
The Grandstream GXV3175v2 is a 7-inch touchscreen IP phone with Wi-Fi connectivity and a variety of features, supporting a range of audio codecs and video codecs (H.264, H.263 and H.263+). One of the features supported on the GXV3175v2 that is described in this FAQ is "video preview". This is a video preview of the doorman before you pick up the call, i.e. you can very easily see who is standing at your door before you pick up the call and start talking to the caller.
| Note: The IP addresses used will always vary depending on your network. In the example below, the IP address 192.168.50.199 for the 2N IP Intercom and the IP address 192.168.50.196 for the Grandstream GXV3175v2 are used. |
How to set up the 2N IP Intercom
Setting up the 2N IP Intercom is very easy. First, it is necessary to create a new user in the blue section directory and assign him a phone number - in our case it will be a direct call (peer to peer) to the GXV3175v2 phone. For this reason, we enter a phone number in the form sip:IP_address (or sip:x@IP_address), where IP_address is the IP address of the GXV3175v2 phone. The setting corresponds to the picture below.
In the next step, go to the "Calling -> SIP 1" section, enable the SIP 1 account and fill in the "Domain" field with the IP address of the 2N IP Intercom.
We can adjust the video codec settings and video resolution. These settings can be made in the section "Calling -> SIP 1-> Video" section, where you can set the maximum resolution for the given intercom model (VGA in this case for the 2N IP Verso intercom), change the frame rate and also the video bitrate. We also enable "Use sendrecv Attribute for Video" in the advanced SPD settings option.
Finally, we need to assign the user to the quick dial button of the 2N IP Intercom in the section "Calling -> Dialing-> Quick Dial Button".
How to set up the Grandstream GXV3175v2 IP Phone
The easiest way to set up this IP phone is via the web interface, but there is also an option to set up the phone directly via the touch screen. The following describes how to set up the phone via the web interface.
In the first step it is necessary to enable and set up the first user account "Account 1". As it was said at the beginning of this article, we will set up the connection between the intercom and the IP phone directly, so we will fill in the "SIP Server" field with the IP address of the 2N IP Intercom to which the IP phone will register. It is not necessary to fill in the authorization name and password in this case.
Next, go to "Call Settings" and make sure that the correct numbering plan is used for the first account. If you see a different numbering plan, then overwrite it according to the image below, or you can copy it from the settings for account 2 or account 3.
Next, go to the "Advanced setting - General settings" section of your phone's advanced settings and make sure the "Use Random Port" box is not checked. If this box is checked, then uncheck it.
In the last step, set "Preview" (i.e. preview the video from the intercom before picking up the call) in the "Maintenance" section. Preview is one of the options that can be selected for incoming call settings (see image below). Once you have set this up and saved it, don't forget to confirm the configuration by pressing the "Apply" button in the top right corner of the screen.
Finally, check that the IP phone is indeed registered to the 2N IP Intercom and test the direct call from the doorphone to the intercom and back.
