In certain situations you want to load balance SIP traffic between multiple SIP endpoints. These SIP endpoints are typically a Session Border Controller (SBC) in your organization or an upstream SIP provider. In any case, you need some logic that will distribute the traffic between the SIP endpoints. In the FusionPBX world (which is based on FreeSWITCH) this module is called Distributor (mod_distributor). In this article we will explain how to configure it.

Assumptions

• You have at least two gateways defined within FusionPBX, which represents the SIP endpoints that you want to distribute traffic between.

Configuration Steps

1. Login to FusionPBX and make sure the mod_distributor module is enabled. You can do so by going under Advanced -> Modules. Distributor should be an option to choose from, but should be disabled.  It will need to be enabled. “Enabled” should read True on the distributor line once it’s enabled.
2. Get Gateway ID’s – right click on the Gateway name and click “Copy Address”. Open up a text editor and paste the address. The Gateway ID is the string after “id=” in the URL. Do this for all of the gateways you want to distribute traffic too.

3. Changing the mod_distributor config xml:

• SSH to your FusionPBX server, make your way into the /etc/freeswitch directory
• Using your favorite editor, edit autoload_configs/distributor.conf.xml and add the following:

<list name="my_list_001" total-weight="2">
<node name="978fefdd-45cd-4457-8ecd-5d82eaea3b12" weight="1"/> <!-- my_gateway_001 - its just comment with actual GW name -->
<node name="1a8d448d-e06e-2dab-b6f9-4421a98e4d8e" weight="1"/> <!-- my_gateway_002 -->
</list>

4. Save and run the following commands from the FreeSWITCH cli

fs_cli > reloadxml
fs_cli > distributor_ctl reload

5. Updated your Outbound Routing setting. You have something like this now: But, you want to change the last line to something like this: The Distributor command above takes a string value that contains a list that was defined in distributor.conf.xml and returns a gateway based on the weight defined in the configuration. In this case, “my_list_001” is the list used. This module can be used for other use cases where you need to generate random/weighted values.

We are introducing a new API that will enable the provisioning of extensions within a backend media server. The API will provide an abstraction layer for provisioning different backend media servers. The first release will focus on FusionPBX.

dSIPRouter has a concept of an Endpoint Group. An endpoint group can be mapped to a FusionPBX Cluster. When this happens the domains from FusionPBX is automatically sync’d with dSIPRouter. We will leverage the existing connection to enable the ability to provision and update Domains and Extensions within FusionPBX. In the future, we will support FreePBX and other media servers as well. Hence, giving users one API for provisioning users and dSIPRouter handles the complexity of translating the request into the backend media server.

The feature will be available in 0.642. You can provide comments and feedback on the API by submitting comments in the GitHub issue which can be found here

The API endpoints for this release are:

/mediaserver/domain/
/mediaserver/extension/

The Payload for this release:

Payload for Domain

{
   domain_id:
   name: string,
   enabled: boolean,
   description: string,
   config_id: endpointgroup_id | conf_id
}

Payload for Extension

{
    type: single| multiple,
    num_of_extensions: integer,
    attributes: {

      domain_id: string | null,
      account_code: string,
      extension: string,
      password: string|null ,
      outbound_caller_number: string|null,
      outbound_caller_name: string:null,
      vm_enabled: boolean,
      vm_password: string,
      vm_notify_email: string,
      enabled: boolean,
      config_id: endpointgroup_id | conf_id
    }
}

Example Usage

The following example will provision a new Endpoint Group in dSIPRouter and a Domain and Extension in FusionPBX. Note, that the API will also support updating and deleting as well.

1) The user will create an endpoint group to represent a FusionPBX standalone instance or a FusionPBX cluster

https://{{DSIP_ADDR}}:5000/api/v1/endpointgroups

They will receive an endpoint group id, which will be used for provisioning the backend media server

2) The user can then create a new domain

https://{{DSIP_ADDR}}:5000/api/mediaserver/domain/

{
   domain_id: null
   name: AprilandMackCo,
   enabled: true,
   description: "April and Mack Co,
   config_id: 64
}

The user will receive the domain_id, let’s assume its 98

3) The user can create one user or a set of users. We are going to create 10 users

https://{{DSIP_ADDR}}:5000/api/mediaserver/extension/

{
    type: "multiple",
    num_of_extensions: 10,
    attributes: {

      domain_id: 98,
      account_code: "124-24245",
      extension: "1000",
      password: "starterpassword" ,
      outbound_caller_number: "8889072085",
      outbound_caller_name: "dOpenSource",
      vm_enabled: true,
      vm_password: "94145",
      vm_notify_email: "",
      enabled: true,
      config_id: 64
    }
}

This API will create 10 extensions starting from 1000 with the same attributes. You can also create a single extension.

The purpose of this tutorial is to explain how to configure the Yealink W60P Cordless DECT IP Phone with FreePBX, Asterisk of FusionPBX.  We will assume that you have the extension already configured in one of the aforementioned systems.  Therefore, we will focus on the steps needed to configure the phone.

I must note that the experience with configuring the Yealink W60P was much better then configuring the Panasonic KX-TGP600

The high-level steps needed to complete this are listed below.  We will go into detail for each section.

• Locate Web Management UI IP Address
• Log into theWeb Management UI
• Configure the phone settings via the Web Management UI

Locate Web Management UI IP Address

1. Pickup one of the Handsets that is registered to the base station
2. Click OK
3. Click OK on the (i) Icon
4. Click OK on the BASE option
5. The IP address of the Web Management UI (aka Base station) will be shown

Log into theWeb Management GUI

1. Open a web browser
2. Enter http://<IP address of the Web Management UI>
3. Enter admin/admin as the username and password

Configure the phone settings via the Web Management GUI

1. Click Account
2. Select the Account you want to configure.  We will use Account1
3. Enter in the following required and optional fields:

Required Fields

Line Action

Label

Display Name

Register Name

Username Name

Password

Optional Fields
These fields are only needed if you have a proxy server in front of your media server such as Kamailio or OpenSIP’s

Enable Outbound Proxy Server

Outbound Proxy Server 1

We will go over how to setup the call center module. The call center module is used for creating an inbound queue for connecting inbound callers with agents registered to your system.

1. You will first need to log into your FusionPBX server via the gui

2. Select the Domain in which you would like to set up the call center in.

3. Select Apps→ Call Center→ plus sign(+) to add a call queue.

4. Fill in the necessary information and SAVE:

• Queue name: Reference name for the queue
• Extension: Extension number for the queue. Make sure it is unique for the system.
• Strategy: Strategy is the way the system will hunt for available agents. For example: if longest-idle-agent is selected, the agent who hasn’t been called for the longest time (idle) will be called first.
• Time Base Score: This is for whether you want to add the extra seconds from the call being established to the agent call time or not. System will add it where queue will keep the time from when the queue is reached.
• Tier Rules Apply:  Select True if you want to apply the tier rules which we will setup later

All the others fields are pretty much standard. If you would like detailed information for each field you may find it here.

 

 

1. Click “back’ to return to the Call Center Queue then on the top right corner, Click Agent

2. Click the plus sign (+) to add agents in the Call Center Agents screen.

3. Fill in the necessary fields:

• Agent Name: Select the corresponding account you have created

• Type: two types supported, callback and uuid-standby. callback will try to reach the agent via the contact fields value. uuid-standby will try to directly bridge the call using the agent uuid.

• Contact: Select the extension you want to associate with that agent

• Status: You can select status from here but it will be interacting with it later so its not an important field for now

• Agent Logout: This is where you can select a time of the day where automatically the agent will be logged out. As it says it requires a service to enforce it.

 

While in the Call Center Agent screen you may also add a Agent ID and Password if you would like the agents to be able to log in on their own.

Note: Agent ID can be a string of numbers that will be used to select via the telephone diakpad.

Agent Call Center Log in

Agents can login to call center with *22 from the phone (hardphone or softphone) or via the FusionPBX web interface. Admin and Super Admin accounts can also log other agents in or out.
