Configuring Grandstream GXV3140

For those wanting to use the video capabilities on this device please note that this is ONLY possible with Callcentric to Callcentric, Callcentric to SIP and SIP to Callcentric calls. We do NOT support video calling to PSTN numbers. Note that if you dial the number of another Callcentric user this is considered an IP call and as such video should be supported if both endpoints support the same video codec(s).

This device has many functions and features. In this setup guide we are primarily concerned with connecting to your Callcentric account in order to receive and place calls. Support for video is possible; however please note that this is NOT guaranteed. We will use the web interface, even though you can also use the built in GUI.

We recommend that you read each step through in its entirety before performing the action indicated in the step.

STEP 1

Booting up the GXV3140

Startup your phone if it hasn't already been started. Once the device is available please take note of the IP address.

Once you have the IP address please open your favorite browser and enter this address. Login to your device with admin as the username and admin as the password, or if you have specified a different username/password you may use this.

STEP 2

Configuring your Callcentric account

We will now configure an account and enter the required credentials, such as your Callcentric number, password and SIP server. Click on the account you would like to configure Callcentric for and enter the following:


Setting	Value
Acccount Active	Checked
Account Name:	Callcentric
SIP Server	sip.callcentric.net
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.
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.
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.
Voice Mail UserID	1777MYCCID, where 1777MYCCID is the 1777 number assigned to you by Callcentric
Name	Your Name

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

Configuring extra settings

We will now configure extra network settings, codecs and our outbound proxy.

Configure the following under SIP Settings:


Setting	Value

Start Video Automatically	Yes
DTMF	RFC2833
Preferred Vocoder	PCMU,PCMU,G729A/B

Every thing else should remain at the default values.

Finally switch to the Call Settings tab and set the following:


Setting	Value
Dial Plan Prefix:
DialPlan	{[x*]+}

Everything else should remain the same.

Make sure to apply the changes you made by clicking on the Apply button at the top of the page:

STEP 4

Once you have completed the above your device should show that the settings are being applied. Once the device has finished, you may may check your status by clicking status at the top of the page. You should see the following:

If you do not see that your account is registered please double check that you entered your 1777 number and SIP password correctly. Please remember to allow your device time to apply the settings.

STEP 5

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).
