Introduction

FreeSBC Hosted PBX Example (see FreeSBC:Hosted PBX) provides you a step by step Hosted PBX Configuration of FreeSbc systems, using the Web Portal configuration tool. What will be discussed here, with guide for example configuration, is when there are multiple domains per PBX or even several PBXs with different domains. This configuration is basically the extension of what is configured in single domain /hosted PBX, that including the repeatedly setting of different domains, followed by specific routing for different domain destinations.

Hosted PBX Example

Hosted PBX topo 1.png

From above, instead of one Hosted PBX, there will be several Hosted PBXs like Hosted PBX1, Hosted PBX2, Hosted PBX3, etc. And each Hosted PBX will use its own domain like example1.com for PBX1, example2.com for PBX2, and so on. This multiple domain scenario can also be applied to single Hosted PBX with different several domains that will be using the same configuration.

From external over the WAN, different phones belonging to different Hosted PBXs registering to domain corresponding to the PBX/Registrar the phone subscribing to.

SIP NAP

A Network Access Point or NAP represents the entry point to another network or destination peer (e.g. SIP proxy, SIP trunk, etc)

SIP NAP Configuration for Local Area Network

To create a new NAP:

1- Click NAPs in the navigation panel

NAP NavigationMenu.png


2- Click Create New NAP

3- Create the new NAP:

  • Enter a name for the NAP
  • Click Create

SIP Server NAP Create.png


4- Verify that the NAP was successfully created message appears

5- Associate a SIP transport server with the new NAP:

  • Select a SIP Transport Server from the Available list
  • Click "<<" to associate the LAN_SIP_TS with the NAP

6- Enter SIP Server proxy address:

7- Associate a Port range with the new NAP:

  • Select a port range from the Available list
  • Click "<<" to associate LAN_Vlan:0 Port range with the NAP

9- Configure settings for the following parameter groups as required:

  • Registration Parameters
  • Authentication Parameters
  • Network Address Translation
  • SIP-I Parameters
  • Advanced Parameters
  • Click Save

Access Control List

FreeSBC will automatically create Access Control List for each NAP you created.

If you double-click one of the created ACL, you will see FreeSBC only accept the calls if source IP matches. In this sample; the calls from 192.168.1.10 will accepted only.

SIP DOMAIN

A SIP domain represents a grouping of devices (or users) that can communicate with one another. You must configure SIP Registration Domain for your system. The first step in doing so is to create a SIP Domain:

Create New SIP Registration Domain

1- Click SIP Domain in the navigation panel

SIP Domain NavigationMenu.png


2- Click Create New Domain

3- Create the new Domain:

  • Enter a configuration Name for this domain.
  • Enter a Domain Name for the SIP Registration Domain (the domain can be an FQDN or an IP address)
  • Set the number Maximum Registered Users for this domain
  • Set the Expires value used by SBC when the remote device doesn't supply one (Default Contact Expire)
  • Select Routing Method the system will use to route calls to registered users (if enabled in routing scripts).
    • Register source: Sends SIP Invite to the registering source IP address.
    • Contact: Sends SIP Invite to the 'contact' from the Register message.
  • Set the Default Contact Expiration, this value will be used when no Expires value is supplied by the user agent.
  • Set the Minimum Contact Expiration, this is the minimum Expires value that can be supplied by a user agent. Lower values will be rejected with a 423 'Interval too brief' response.
  • Set the Maximum Contact Expiration, this is the maximum Expires value that can be supplied by a user agent. The higher value is replaced by this parameter.
  • Forwarding Parameters:
    • Select the Registration Forwarding Mode to the registrar:
      • Contact Remapping: Changes the user and the IP address.
      • Contact Passthrough: Doesn't change anything. Enables devices to be contacted directly without going through the SBC.
    • Set Minimum Registrar Expiration, this is the minimum Expires value sent by the SBC to the registrar. If a user agent 'Expires' value is greater than this parameter, the SBC will do rate adaptation between the user agent and the Registrar.
    • Set Maximum Pending Register Forward, the maximum number of simultaneous pending register requests allowed for this domain. New REGISTER request is being refused passed this threshold.
    • Set Maximum Simultaneous Register Forward, the maximum number of simultaneous active register requests allowed for this domain. New REGISTER request is being refused passed this threshold.
  • Click Create

5- If your registrar has multiple domains, you need to create all the domains one by one.

Create New SIP Registration Registrar

A SIP registrar represents a SIP endpoint that provides a location service. You must configure SIP Registrar for your system. The first step in doing so is to select your SIP Domain:


1- Click on your domain in the SIP Domain List

2- Click Create New SIP Registration Registrar

3- Create the new SIP Registration Registrar

  • Enter a Name for the SIP Registration Registrar
  • Select pre defined SIP Proxy NAP from drop-down menu
  • Click Create

4- Verify that the Sip registration registrar was successfully created message appears

Associate a SIP Domain with the new NAP

Associate a SIP Domain with the new NAP. If you have more then 1 registrar domain using the same registrar you can associate all of them with the NAP:

  • Select a sip domain from the Available list
  • Click "<<" to associate the SIP Domain with the NAP

Call Route

You must set up call routing for your system. Call routing refers to the ability to route calls based on criteria such as origin, destination, time of day, service provider rates, and more.


Route Configuration for Remote Phones to SIP Server

1- Click Routes in the navigation panel

2- Click Create New Static Route

3- Create the new route:

  • Enter a RoutesetName for the route
  • Select SIP_REMOTE, to match calls from Trunk NAP
  • Select SIP_SERVER_NAP
  • Click Create

3- Create the new route:

  • Enter a RoutesetName for the route
  • Select SIP_SERVER_NAP, to match calls from Trunk NAP
  • Select (By registered user)
  • Click Create

Activating the Configuration

Changes made to the configuration of the FreeSBC units are stored in the OAM&P Configuration and Logging database. In order for changes to be used by the system, they must first be activated. This is done at the system level and accessed from the Navigation panel.

Check the following link for activating the configuration;
