pbxnsip is a windows and linux based software PBX offering all the advanced features of a full featured PBX including calling queues, auto attendants, call forwarding, parking and many others. pbxnsip requires a license to operate so users of this software will have to purchase a license directly from the pbxnsip website or a reseller.

This setup guide is intended to show the most basic configuration of the pbxnsip PBX. For more advanced configurations and features you can combine the basics included in this guide along with the pbxnsip documentation.

Please note, Callcentric is not responsible for preventing unwanted physical or remote access to your IP PBX. If your IP PBX is compromised, you will be responsible for all associated damages.

Please be sure to read this guide regarding securing your IP PBX solution.

Configuring pbxnsip

Here we will configure pbxnsip through the web interface to properly route both incoming and outgoing calls to and from Callcentric. The information presented in this document is based on version 3.3.1.3177 (Win32) of the pbxnsip software. This guide assumes that you have installed pbxnsip and that the pbxnsip install steps were completed properly including obtaining the proper license. This guide also assumes that you have administrative access to the pbxnsip administration interface.

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

STEP 1

Add a new Domain

If you haven't already please follow this step to add a new domain to your pbxnsip PBX. Otherwise you may skip this step.

Login to the pbxnsip administrative interface
Select "Domains'" from the top of page
Select "Create" from the sub menu
Read the instructions for adding a new domain
Enter "localhost" in the "Primary Name" field
Enter "localhost" in the "Alias Names" field
Click "Create" to create a new domain

STEP 1b

Select the domain

Now you will need to select the domain you wish to configure. Note that your amount of users may differ from the number shown below.

Click "Domains" from the top of the page
Select the domain you wish to edit. In this case please select "localhost" from the Domains list

STEP 2

Trunk Configuration

In the context of this guide a trunk is used to route calls to or from your pbxnsip PBX and Callcentric

Select "Trunks" from the navigation options. You will either be shown a list of trunks you have already configured or an empty list of trunks
Scroll to "New Trunk" and Enter "callcentric" into the "Name" field
Select "SIP Registration" as the value for "Type"
Click "Create"
When the page reloads click on the edit icon next to the trunk you wish to edit, in this case the "callcentric" trunk.

Enter the following information in the appropriate fields:


Display Name	[Enter your name or Company name here]
Account	1777MYCCID
Registrar	sip.callcentric.net
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.
Password (repeat)	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.
Outbound Proxy	sip.callcentric.net
Trunk ANI	Verified callerID or DID on account
Override Codec Preference	G711U, G711A and G729A

Latest versions of pbxnsip version3 include a new method for routing incoming calls. If you have the field below please configure the following:

Send call to extension !([0-9]*)!\1!t!100

Where 100 can be any extension of your choice
Click "Save" to add your new SIP trunk to your pbxnsip server
When the page reloads click on the "List" link from the navigation menu to see that your new trunk has successfully registered to Callcentric's servers

STEP 3

Configure Dial Plans

Here we will add a default dial plan for the localhost domain if there is no default dial plan.

Note: Currently in order to send star (*)/feature code numbers to Callcentric you will have to use an outside line qualifier. Here we use 9. We also use 9 to send any call to Callcentric:

Select "Dial Plans" from the navigation menu
Add a new dial plan and call it "callcentric"
Click "Create". The page will then reload
Click on the edit icon next to the "callcentric" dial plan to edit it
Enter the following dial plan

Pref Trunk Pattern Replacement

200 callcentric 9*

100 callcentric 9(\*)([0-9]*).* \1\2

Click "Save" to add your new dial plan pattern

STEP 4

Add an Account/Extension for calling

An extension in pbxnsip is an account that provides a number which another UA (software or hardware used for calling) can connect to in order to make and receive calls.

* If you have already configured an extension then you may skip to editing the extension. Then in the next step (Inbound Call configuration) you may use your pre-configured extension.

Select "Accounts" to add a new extension which will connect to your pbxnsip server
Select "Create" on the top of the page to begin the process
Select "Extension" from the account type drop down box
Enter 100 for the first extension number
Enter "First Extension" in the "Name" field. Later you may enter a unique identifier of your choice
Enter your desired password in the "Password" field. You will use this password when configuring your desired UA later in order to connect to your pbxnsip PBX
Enter an optional email address in the "Email" field for the person using this extension. Here we have left it blank
Click on "Create" on the bottom of the page to add your new extension to your pbxnsip server
When the page reloads select "Show List" from the navigation
Click on the edit icon next to the 100 extension, or your pre-configured extension
Set the "Dial Plan" option to "callcentric", which is the dial plan we created earlier
Click on "Save"

STEP 5

Inbound Call Configuration

Inbound configuration can be extremely complex. With an inbound route you are given the flexibility to send incoming calls to a whole range of destinations. For example you may route an incoming call to a specific extension, to a ring group or to an IVR. In this section we are going to setup an inbound route, which will simply route those calls to a hunt group consisting of your 100 extension. Later on you can configure more complex routing schemes.

Select "Account" to configure the routing of calls to your Callcentric account
Select "Create" at the top of the page to begin adding a new hunt group
Select "Hunt Group" for the "Account Type"
Enter your 1777XXXXXXX Callcentric account number in the "Account Names" field
Click on "Create" on the bottom of the page to add your new "Hunt Group" to your pbxnsip PBX
When the page reloads click on "Accounts" then click on "List" and finally click on the edit icon next to the 1777XXXXXXX hunt group you just created
In the "Stages:" section add the 100 extension to the "Stage 1 Extensions" list and set the timeout to 30, or your desired timeout limit which is in seconds
Set the value for the "Dial plan for outbound calls" field to "callcentric", which is the dial plan we created earlier
Click "Save"

STEP 6

Configure and test UA

Choose your desired UA
Use the IP address or hostname for your pbxnsip PBX along with "100" (the extension created earlier which is the username) and the password for the 100 extension to connect to your pbxnsip PBX
Next you will want to try placing test calls to and from your pbxnsip PBX using the UA currently connected to your newly created extension (100). To perform test calls please follow this link. Remember to use 9 as your outside line qualifier.
