Grandstream GXP2200 product manual


Configuring Grandstream GXP2200
These instructions are based on Grandstream GXP2200 software version 1.0.1.30; hardware revision 2.2A; Android version 2.3.5. If you are running a different revision some menus and settings may be different. These instructions are also based on using the GXP2200 in its factory default configuration, which obtains a dynamic IP address automatically from your router using DHCP. For information on configuring your GXP2200 with a static IP address please refer to the GXP2200 user manual.

The GXP2200 is fully featured and allows you to edit your configuration and add/remove accounts from the phone itself, however for the purpose of this guide we used the web interface to add an account.

We recommend that you read each step through in its entirety before making any changes to your phones configuration.
Step 1 Connecting the GXP2200 to your network
Connect your GXP2200 to your router using the included Ethernet cable, be sure to plug it in to the LAN port of the phone. Once that's completed, plug the AC adapter to your phone then the other end to an available power outlet.

Step 2 Accessing the web configuration
Once you have powered up your device plus wait 60 seconds for GXP2200 to fully boot up.

On the LCD Screen of the phone there should be an empty window that you add accounts to, you will see an IP address at the top of this window in a format similar to 192.168.1.10, note that the numbers in the IP address may actually be different depending on your network.

On your computer open a web browser like Chrome, Firefox, Internet Explorer, or Safari, and enter the IP address that you see on your phones LCD screen in the address bar(the same location where you enter web addresses).

Step 3 Logging in to the GXP2200
You should now see a page that looks like this:



Enter your GXP2200's user name and password in to the fields on the screen. By default the username and password should both be admin. Once you have logged in you should see a page that looks like the screen shot below:



Step 4 Configuring your Callcentric account
We will now configure one of the lines on the GXP2200 to work with your Callcentric account. To begin, and assuming you are still on the Status page shown in the previous step, please click the Accounts link on the top of the page as highlighted below:



From there you should be brought to the Account 1 -> General Settings page. Once there make the following changes:

SettingValue
Account Active:Checked
Account Name:My Company
SIP Server:callcentric.com
SIP User ID:This is either the default extension 1777MYCCID OR 1777MYCCIDEXT, where 1777MYCCID is the 1777 number assigned to you by Callcentric and EXT is the three digit extension you are trying to register this UA to.

For example: 17770001234101 would register to extension 101 on account 17770001234.

You cannot register to your account using only the extension number.
SIP Authenticate ID:This is either the default extension 1777MYCCID OR 1777MYCCIDEXT, where 1777MYCCID is the 1777 number assigned to you by Callcentric and EXT is the three digit extension you are trying to register this UA to.

For example: 17770001234101 would register to extension 101 on account 17770001234.

You cannot register to your account using only the extension number.
SIP Authenticate Password:Enter your extension SIP Password here. Your extension SIP password is the password you created for the extension you are trying to use. You may edit the SIP password you wish to use in by logging into your My Callcentric account and clicking on the Extension menu link and then modifying the appropriate extension.
Name:1777MYCCID, or any name you choose


Your General Settings configuration should look similar to the one shown in the picture below:



Step 5 Configuring your Callcentric Network Settings
Once you have saved your general account settings click Network Settings on the left and make the following changes:

SettingValue
Outbound Proxy:callcentric.com
Secondary Outbound Proxy:callcentric.com
DNS Mode:SRV
NAT Traversal:Keep-alive


Your Network Settings page should then look as follows:



Once the changes have been made click save then at the top of the page select Apply and wait 30 seconds then you're done.

Step 6 That's it! You can now make a phone call.
You can make a test call to 17771234567, or if you are signed up for one of Callcentric's rate plans you can place a call to a traditional landline or mobile phone by dialing either:
1 + the area code and number for calls to the US
Or
011 + the country code, area code, and number for calls worldwide (you may also use 00 instead of 011).

To test inbound calls from Callcentric to your GXP2200 installation, follow the directions listed in this FAQ.
