_images/sipchan_general.png

5. Next you will enter the configurations under the SIP Settings. Here you will enter the SIP settings for outgoing calls by selecting the Outbound tab. You will need the following information: The following fields needs to be entered

Field Value
Host <host name or IP address of dsiprouter>
Username <Specified in dsiprouter@domainname>
Secret <Specified in dsiprouter>
Type peer
Context from-trunk

The domain name has to be included and correct.

_images/chansip_outgoing.png

NOTE:** Type <context=from-trunk> underneath the <type=peer> in the Peer Details box if it does not appear.

  1. Next you will enter the configurations for incoming by selecting the Incoming tab in the SIP Settings. Here you will enter the SIP settings for inbound calls. You will need:

User Context: This is most often the account name or number your provider expects. In this example we named it “inbound”. The following User Details needs to be entered:

Field Value
Host <host name or IP address of dsiprouter>
Insecure port,invite
Type peer
Context from-trunk
_images/chansip_incoming.png

In the Register String enter: <username@domainname>:<password>@<ip address or hostname>. In this example it would be sipchantest@sip.dsiprouter.org:HFmx9u9N@demo.dsiprouter.org. The domain name has to be included and correct.

_images/register_string.png
  1. Click Submit
  2. Be sure to click the Apply Config button after submitting to confirm.
_images/apply_config_button.png

You will now be able to see the new chanSIP added in the truck.

  1. Next you will need to setup an outbound route. Select Connectivity→ Outbound Routes. Click the “+” sign to add a outbound route. In this tab you will need to enter:
Field Value
Route Name Type desired name
Route CID Number you want to appear on caller ID
Trunk Sequence for Matched Routes Trunk name (select from drop down box)
_images/outbound_routes_chansip.png

10. Click the Dial Patterns tab to set the dial patterns. If you are familiar with dial patterns, you can enter the dial patterns manually or you can click the Dial Patterans Wizard to auto create dial patterns if you like. You can choose 7, 10 or 11 digit patterns. Click Generate Routes.

_images/chansip_dial_wizard.png

Dial pattern is set to your preference. Prefixes are optional, not required.

_images/chansip_dial_pattern.png
  1. Click Submit and Apply Config button.

Assuming you already have an extention created in your FreePBX, you can validate incoming/outgoing calls by configuring a softphone or a hard phone. Below is an example of the information you would enter if you use a softphone: In this example we are using Zoiper. Once you’ve downloaded Zoiper application on your PC or smart device you would enter the following to configure the soft phone:

Field Value
Username <extension>@<siptrunkipaddress>
secret <Password of that extension>
Hostname <IP address of your FreePBX> (should autofill)

Note Skip Authenication and Outbound Proxy

You should now be able to make a inbound and outbound call successfully!

Using SIP Trunking - FusionPBX IP Authenication

The following screenshot(s) shows how to configure a SIP trunk within FusionPBX for IP Authenication.

  1. Log into your FusionPBX.
  2. Click Accounts –> Gateways–>Click the + sign to add a gateway/SIP Trunk. The only fields you will need to fill here are:
  • Gateway= Name of the SIP Trunk
  • Proxy= IP address of the SIP trunk
  • Register= Change to False because you are using IP authenication.
_images/sip_trunking_fusionpbx.png _images/sip_trunking_fusionpbx_2.png
  1. Click Save
  2. Click DialPlan–>Outboung Routes–>Click the + sign to add a outbound route. Here you will enter in the following fields:
  • Gateway= Name of the SIP Trunk
  • Alternate gateways (if applicable)
  • DialPlan Expression= 11d (standard setup in FusionPBX). To change the dialplan expression click on the dropdown box where it says “Shortcut to create the outbound dialplan entries for this Gateway.”
  • Description= (if desired)
  1. Click Save
_images/outbound-routes_fusionpbx.png _images/outbound-routes_fusionpbx_2.png

NOTE To make these changes global for ALL domains for this SIP Trunk: reopen outbound routes and change the Domain to Global and the Context to ${domain_name} as shown below.

FusionPBX Hosting

Here we will demostrate how to setup dSIPRouter to enable hosting FusionPBX. We have built-in support for FusionPBX that allows domains to be dynamically pulled from FusionPBX.
  1. Login to dSIPRouter
  2. Click PBX(s) and EndPoints
  3. Click ADD; enter the following fields
  • Friendly Name (opional)
  • IP address
  • IP Auth
  • Click to enable FusionPBX Domain Support
  • FusionPBX Database IP or Hostname
  1. Click ADD
_images/fusionpbx_hosting.png
  1. Click Reload Kamailio. (when changes are made reload button will change to orange)
_images/reload_button.png
  1. Access your FusionPBX database via ssh.

7.Run the command as illustrated in the “Edit your PBX Detail” window as root on the FusionPBX server. Replace <ip address> (not including the brackets) with the IP address of the dSIPRouter server you’re adding. Command line will look simulair to the following picture. NOTE After you have entered the first two lines of commands you will not see a form of reply. If command is entered correctly it will return back to your root line. If the command line is incorrect you will receive a “command not found” error message. Recheck the command line and IP address.

_images/fusionpbx_domain_support.png

After the command is run you should now be able to see the domains of that PBX in dSIPRouter.

_images/list_of_domain.png

You can test PBX Hosting is valid by configuring a softphone or a hard phone. Below is an example using a softphone:

Now that domains have been synced in dSIPRouter you are able to register a softphone. In this example we are using Zoiper. Once you’ve downloaded Zopier appliaction on your PC or smart device you would add:

  • username (extension@domainname)
  • password (password of that extension)
  • outbound proxy (IP address of the dSIPRouter)
_images/zoiper_screenshot.png

Provisioning and Registering a Polycom VVX Phone

Now that domains have been synced in dSIPRouter you are able to register a endpoint/hard-phone. In this example we are using a Polycom VVX410 desk phone.
  1. Log into your FusionPBX box
  1. Update the “outboundProxy.address” of the template with the IP address or hostname of the dSIPRouter in the provisioning editor.
_images/outbound_proxy.png
  1. Assign the phone to a template.
_images/assign_template.png
  1. Configuring the Provisioning Server section of the phone. Enter the appropriate information into the fields.
  1. Server Type (dSIPRouter uses HTTP by default)
  2. Server Address
  3. Server Username (device provisioning server name)
  4. Server Password
  1. Click Save
_images/provisioning_server.png
  1. Reboot the phone

FreePBX Hosting - Pass Thru Authentication

Here we will demostrate how to setup dSIPRouter to enable hosting FreePBX using Pass Thru Authentication. FreePBX is designed to be a single tenant system or in other words, it was built to handle one SIP Domain. So, we use dSIPRouter to define a SIP Domain and we pass thru Registration info to the FreePBX server so that you don’t have to change how authentication is done. However, this will only work for one FreePBX server. If you have a cluster of FreePBX servers then use “Local Subscriber Table” authentication. The value of having dSIPRouter in front of FreePBX is to provide you with flexibility. After setting this up you will have the ability upgrade or migrate users from one FreePBX instance to another without having to take an outage. The following video shows how to configure this. The steps to implement this is below the video.

Steps to Implement

  1. Click PBX and Endpoints
  2. Click Add
_images/freepbx-pt-add-pbx.png
  1. Reload Kamailio
  2. Click Domains
  3. Click Add
_images/freepbx-pt-add-domain.png
  1. Reload Kamailio
  2. Register a phone via dSIPRouter - notice that we used the hostname of dSIPRouter as the Outbound Proxy. This forces the registration thru the proxy.
