Grandstream GXV3175 Multimedia Phone

The Grandstream GXP3175 is compatible with the OnSIP boot server and as such, you should use those instructions to register the phone. 

Prerequisites

Phone network configuration completed.

The following instructions assume your phone has successfully booted and completed network configuration including obtaining valid IP addresses for itself, an IP gateway and DNS servers either via DHCP, manual or other means (refer to your phone's documentation) and that your phone is running with factory defaults.

Grandstream now allows public download of documentation and software at:
http://www.grandstream.com/firmware.html

The very first thing you will want to do is set the firmware to the most recent available. Log into the phone's IP address. The username and password will both be 'admin.' From there, navigate to "Maintenance" at the top and then to "Upgrade" on the right. You will want to use the IP address information given in the link above.

Note: There is a bug in the current version where the "Account Name" text cannot be edited. You must restore the phone to factory default (restore VoIP Settings) to reset the "Account Name" field. The WWW interface will allow you to change the field, but the phone will not accept the changes without the reset.

Upgrade via and server paths

From there, you'll need to reboot the phone. Navigate to the Dog-Eared page-turn in the upper right of your browser, then select "Reboot".

Dog-Eared page-turn and reboot 

Step 1: Gather information for each user.

Each user has a set of credentials which will be needed to configure each phone. For each phone that you are configuring, obtain the following:

  • "SIP Address" (Address of Record)
  • "SIP Password"
  • "Auth Username"
  • "Username"
  • "Domain"
  • "Outbound Proxy"

You can find this information in the user detail pages under the "Users" tab in the "Phone Configuration" section.

Step 2: Log into your Grandstream phone through a web browser

The IP address of the phone is given on the main screen when the phone obtains an IP address. The default username and password are both "admin". Once you've logged in, select "Account 1" from the "Account" tab 

Step 3. Enter your user information from Step 1.

For most setups, you will need to simply configure "Account 1". If you are trying to configure multiple users or multiple line appearances, you can repeat the steps below for each of the identities you are configuring.

General settings

  • Account Active: Yes
  • Account Name: Whatever you would like others to see when you call them.
  • SIP Server: "Domain"
  • SIP User ID: "Username"
  • Authenticate ID: "Auth Username"
  • Authenticate Password: "SIP Password"
  • Name: Whatever you would like others to see when you call them.

Hit "Save" at the bottom and then navigate to "Network Settings" on the left side of the screen.

Note: The phone has a timeout on the interface. If you hit "Update" and the phone returns to the login page and your changes were not saved, it timed out. Make your changes more quickly and hit "Update" to save them.

Network Settings

We handle all NAT related issues. So, make sure to turn off any NAT settings in order for your phone to communicate properly with our servers.

Confirm the following settings:

  • "Oubound proxy:" sip.onsip.com
  • DNS Mode: A Record
  • SIP T2 Interval: 4 sec
  • NAT Traversal: No

Network settings

Note: If you find that you are at times unable to receive phone calls, your firewall may be blocking inbound packets. You can set NAT traversal to "Keep-Alive" rather than "NAT NO," This will cause the phone to periodically send out data in an attempt to keep lines of communication open between it and the outside world.

Hit "Save" and navigate to "Codecs" on the left.

Codecs

Set the codecs as demonstrated in this screen shot:

Codecs

Codec Note: Doing interoperability testing through video phones of various manufacturers we have found that as of January 2011 that most of the devices we tested work well if both are set to video codec h.263 rather than h.264 or h.263+1998 (h.263+).

Hit "Save" and navigate to "Call Settings" on the left.

Call Settings

We found that default dial plan did not allow the phone to work for most "real world" dialing as assumed by OnSIP. We have set our dial plan to "{ x+ | *x+ | *xx*x+ }" which covers three and four digit dialing and both international and 11 digit dialing as required by OnSIP.

Hit "Save" and click on the "Advanced Setting" tab at the top.

Advanced Setting

Remove the default "STUN server" and leave it blank

STUN server

Hit "Save" and click on the "Maintenance" tab at the top, then navigate to "Time Settings" on the left.

Time Settings

Change the NTP server to "pool.ntp.org" then set your time zone and any other preferences you may have.

Time settings

Hit "Save" and then reboot. 

Step 4. Confirm that your phone is registered.

In the Admin Portal, click on the "Users" tab. You will see a green "online" notation next to each user with a registered phone.
