| Configuring the UCM6204 |
|
These instructions are based on Grandstream UCM6204 firmware version 1.0.15.16. If you are running a different firmware version (or a different model of the UCM62xx series of products), some of the menus/settings may be different.
In this guide we will go through configuring the UCM6204 through the web interface to properly route both incoming and outgoing calls to/from your Callcentric account.
We recommend that you read each step through in its entirety before performing the action(s) indicated within the step.
|
 | |
| STEP 1 |
Adding an extension |
|
Login to the UCM6204 administrative interface and click on the PBX option that is located on the top menu bar. From there, locate the heading Basic/Call Routes which is located on the side menu and click on Extensions.
Click the Add button located at the top of the Manage Extensions page.
On the Create New Extension page, enter the following:
- Your Extension Type (for this option, we've selected SIP Extension)
- Extension Number
- Extension Name
- Password
Note: You're free to modify the other settings on this page, however please note that the settings we provide in this guide have been tested/confirmed to work properly.
Once you've entered your credentials for this extension, click the Save button to continue. Then click on the blue button labeled Apply Config at the top of the screen to apply the changes you've just made.

| STEP 2 |
Adding a VoIP Trunk |
|
Next we will define a new SIP trunk on your PBX. To proceed, select VoIP Trunks on the menu bar on the left side of the screen and select Create New SIP Trunk. In doing so, a Create New SIP Trunk pop-up window should appear.
Once the Create New SIP Trunk pop-up window loads, locate the option Type and select Register SIP Trunk from the drop down menu. As indicated in the screenshot below, please specify the following information:
| Setting | Value |
| Type | Register SIP Trunk |
| Provider | callcentric |
| Hostname | sip.callcentric.net |
| Keep Trunk CID | checked/enabled |
| NAT | checked/enabled |
| Need Registration | checked/enabled |
| Allow outgoing calls if registration fails | checked/enabled |
| Username | 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. |
| 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. |
| Auth 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. |
After you've finished entering your settings, click the Save button to continue.
Please re-visit the VoIP Trunks page, and click on Edit (denoted by a "pencil icon"). In doing so, a Edit SIP Trunk pop-up window should appear. On this page, please configure your settings in-line with those detailed in the screenshots below.
Basic Settings

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

Configuring an outbound route |
|
In this step we will configure an outbound route for your system. To proceed, click Outbound Routes on the menu bar on the left side of the screen and then click the Add button on the loaded page. In doing so, a Create New Outbound Rule pop-up window should appear.

| STEP 4 |
Adding an inbound rule |
|
In this step we will configure an inbound route for your system. You may send incoming calls to any pre-configured location; such as an Extension, IVR, etc... In this example, we will select the extension that you created in Step 1.
To proceed, click Inbound Routes on the menu bar on the left side of the screen and then click the Add button on the loaded page. In doing so, a Create New Inbound Rule pop-up window should appear.
On this page, please configure your settings in-line with those detailed in the screenshot below.

| Privilege Level | Internal |
| Default Destination | Extension - 1000 |
Click on the Save button to continue; then click on the blue button labeled Apply Config at the top of the screen to apply the changes you just made.
|
| STEP 5 |
Configure and test UA (User Agent) |
|
- Choose your desired UA
- Use the IP address or hostname for your UCM6204 along with "1000" (the extension created earlier which is the username) and the password for the 1000 extension to connect to your UCM6204.
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).
