Grandstream DP715 product manual


Configuring Grandstream DP715/710
These instructions are based on hardware version 1.2A running the 1.0.0.8 firmware. This guide is based on the understanding that you are using the DECT Phone in its factory default configuration, which is to obtain a dynamic IP address automatically from your router using DHCP, which is how most people have their home routers configured. For information on configuring your DP715 with a static IP address, please refer to the DECT Phone's user manual.

We recommend that you read each step through in its entirety before performing the action indicated in the step.
Step 1 Powering up and logging into your device
Connect your router with the supplied Ethernet network cable to the DP715. Now connect your phone to the DP715. Finally plug the supplied power cable into the DP715.

Once the device is fully powered up, pick up the phone connected to the DP715 and dial the * key 3 times. Once you hear the menu enter 0 2 on your phone. You will now hear a message giving you the IP address of your DP715. I.E.: 192.168.001.010. Record this information.

Step 2 Logging into your DP715
Open a web browser on your computer such as Internet Explorer and enter the IP address you heard above in the address bar (I.E. where you would normally enter www.yahoo.com).

Please note: some browsers will require you to remove leading zero's ( 0 's ) in the IP address. For example if you heard 192.168.001.010 you should change this to 192.168.1.10.

You should now see a page that looks like this:



Enter the password for the DP715 in the password field. The default administrator password for the DP715 is admin. You should be taken to a splash page showing your device's registration status, firmware... etc:



Step 3 Configuring your Callcentric Profile settings
To do this click on the PROFILE 1 tab and configure the server settings for your Callcentric account. In the top section of the profile page you will need to fill the following fields:

SettingValue
Primary SIP Serversip.callcentric.net
Outbound Proxysip.callcentric.net
SIP TransportUDP
NAT Traversal (STUN)no, but send keep-alive
Outgoing Call Without Registrationno


Your configuration should look similar to the one shown below:



After filling in the fields as directed click the Update button at the bottom of the page. Your device will reboot. After waiting 30 seconds you should be ready to configure your account credentials.
Step 4 Configuring your Callcentric Account Login Information
To configure your Callcentric username and password click on HANDSETS. Under Handset 1, fill in the following

SettingValue
SIP User IDThis 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 IDThis 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 PasswordEnter 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.
NameEnter your name in this field


These settings should look similar to the ones below:



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 5 Properly rebooting your device
After filling in the fields as directed click the Update button at the bottom of the page.

You will again be taken to a screen indicating that the device is rebooting.



After 30 seconds, click BASIC SETTINGS link listed at the top of the page.

On the Basic Settings page click the Reboot button to reboot your DP715. Please wait at least 90 seconds for the unit to finish rebooting. Once the unit has finished rebooting you should no longer see the light on top of the DP715 blinking red. If the light is no longer blinking red then your unit is configured and ready to make calls.

You should now see that your device is properly registered to your Callcentric account.



If the light on the top of the DP715 is still blinking red, please wait 2 minutes and then unplug the power, wait 10 seconds and plug it back in. If after another 2 minutes the light continues to blink red please verify that the settings you entered into the DP715 in step 9 are correct, and that your internet connection is currently up and running.

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).
