This document details the steps needed to get your x164 switch started.

Contents

Preface

The x164 softswitch is based on yate. The softswitch can be installed on the servers of the x164 customer or is hosted by x164 in the datacenter.

We recommend to install the softswitch as a OpenVZ virtual machine. OpenVZ offers near-bare-metal performance. The advantage of virtualization are: Easy backups, easy migration to different hardware in case of failures or hardware upgrades. x164 provides a OpenVZ template for download which is a ready-configured softswitch.

Softswitch installation

Setup Linux Host for OpenVZ

Use of Debian Squeeze is recommended for its stability, but you can use other Linux distributions as you wish. You can look for the proper option for your machine here. Installation guides are also available for the different supported architectures here.

This website offers a screenshot based tutorial that explains how to make a bare-bones installation without a graphical desktop environment. We suggest to create a separate partition /vz to store the virtual machines, as for example in the following scheme.

Disk partitioning

The recommended partition scheme is the following:

Partition Size File system Comments
/boot 500 MB ext2
swap ~ swap Size should be the same as RAM
/ 20 GB ext4
/vz remaining disk space ext4 OpenVZ virtual machines will be installed in this partition

It is encouraged that you follow the order shown in the table when partitioning.

Updating and upgrading

After completing the installation you should run the following commands:

sudo apt-get update
sudo apt-get upgrade

This ensures you have the latest version of the installed packages.

Remote SSH access

If you want to work on your server remotely from a remote client, it is recommended to use a Secure Shell (SSH) protocol. Install a SSH server:

apt-get install openssh-server

Now you can open the terminal on your workstation and type the following to log in the host machine:

ssh root@[ipAdress]

It will ask you for the hostname's password. From now on you can continue working from your workstation remotely.

Midnight Commander

We recommend using a visual file manager like Midnight Commander (mc) to make working with the command line easier. To install it in your server enter this command:

apt-get install mc
mc

You can find more information about mc in [1]

Webmin installation

It is recommended that you use Webmin to easily configure your softswitch. Run the following command to avoid dependency issues

apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl apt-show-versions python

Then you can download Webmin

wget http://prdownloads.sourceforge.net/webadmin/webmin_1.590_all.deb

and install it

dpkg --install webmin_1.590_all.deb

OpenVZ Installation

Installation for Debian systems is detailed in this tutorial. You can also refer to the OpenVZ installation guide for Debian and other operating systems.

Softswitch template installation

To download the softswitch template just run the following command:

wget http://www.x164.com/index.php/download-and-install

and create the softswitch container.

vzctl create [CTID] --ostemplate nameOfTemplate 

Once you have created a new [CTID].conf file will appear at /etc/vz/conf. There you can set the VM's IP, gateway and hostname as it fits your network, among other parameters. This is an example of what the .conf file should look like:

IDConf.png

Then you can start your softswitch container:

vzctl start [CTID]

Here you can find some of the basic operations needed to work with your container.

Setup softswitch to connect with x164

The softswitch needs to connect to the x164 database to retrieve routing information and to the x164 radius server to send call details records. We will initiate fake calls from a softphone to test whether everything works correctly.


Editing register.conf file

To access the x164 database in realtime from your softswitch you must need a secret key that we issue to you. To find your key, log into https://access.x164.com. Go to the Rating tab and select Gateways in the Action area.

GatewaySecretKey.png

You need to enter the key into the call routines in the softswitch. Go into the /usr/local/etc/yate folder of your installation and open the register.conf file. In this file the string 'hyTnw94^^f' must be substituted by your own secret key for MySQL procedures in yate.

Setup Firewall on Softswitch

The firewall can be setup comfortably with Webmin:

https://softswitchIP:10000

In the Networking/Linux Firewall subsection, Default Action should be set to Drop. Then a new rule must by added by clicking Add Rule. This new rule must be defined like this

AddRuleLinuxFirewallMenu.png

where 11.22.33.55 is the IP of your workstation. The firewall must be opened for all IPs from which you receive VoIP traffic. Now the Linux Firewall menu should look like this:

Press the Apply button to activate the rules.

Verify yate functionality

You can verify that yate is working in principle. Go to the terminal and log into the softswitch through port 29. Using a port which is not the standard ssh port 22 reduces the chance that some weak password is hacked.

ssh root@[softswitchIP]:29

Then see what is happening on the port that will receive the fake call. The softswitch listens on udp port 5061 and not the standard port 5060.

usr/local/etc/yate ngrep port 5061

Now you can attempt a call from a softphone Zoiper

After dialing you should see SIP messages going back and forth between the soft phone and yate. As no subscriber is setup in the system the call will of course fail.

Connection to Radius server

Login into https://access.x164.com and click search in the CDRs tab. The test calls your did should be shown, confirming that the softswitch is connected to the x164 radius server.

Web Configuration of the x164 Service

To get the x164 system started, you must create some new subscribers and set up a block of DID numbers. Once you have done this you can make a test call and verify the system is working properly.

Adding subscribers

We are going to create dynamic and a fixed IP subscribers and set a profile and a rate for both of them. In the following tables the bold fields must be set, the remaining fields may stay empty.

Adding a dynamic IP customer

To see your customers table go to the 'Rating' tab and select 'Customers' in the 'Action' field. This is the example you should follow when they have a dynamic IP address:

Reseller (Automatically generated Id)
Dynamic_ip 1 (Flag for dynamic IP use)
Subscriber user1@domain.com (Subscriber name)
Password verysecret (User password)
Profile PROFCLIENT (Profile name. Links the customer to a profile in the 'Profiles' table)
Blocked 0 (Block subscriber flag)
Pre_location sip/sip: (Protocol used. Will be added before the called number. Write in lowercase)
Post_location (Automatically updated IP address after SIP client registers to softswitch)
Expires (Automatically updated when dynamic IP expires)
Formats (Optional codec formats separated by comma, g729, ulaw, ...)

Adding a fixed IP customer

For fixed IP customers authentication is based on their IP address, so there is no need to provide a password. Also it's necessary to provide the post location field so their calls can be routed by the x164 system.

Reseller (Automatically generated Id)
Trusted Peer 11.22.33.44 (Authorized IP address)
Dynamic_ip 0 (Flag for dynamic IP use)
Subscriber user2@domain.com (Subscriber name)
Profile PROFCLIENT (Profile name. Links the customer to a profile in the 'Profiles' table)
Subscriber_out (In case subscriber provides also termination his carrier name must be set to avoid looping calls)
Blocked 0 (Blocked subscriber flag)
Pre_location sip/sip: (Protocol used. Will be added before the called number. Write in lowercase)
Post_location @11.22.33.44 (Customer's IP address)
Formats (Optional codec formats separated by comma, g729, ulaw, ...)

Linking customer to a profile

Next step is adding a profile, which is used by the system to calculate the price of calls. The 'Profile' field of a customer entry determines the profile it is linked to. Select 'Profiles' in the 'Action' area and add a new one:

Reseller (Automatically generated Id)
Profile PROFCLIENT (Profile name. Links the customers in the 'Customer' table)
Rate PROFCLIENT (Link to profile's rates in the 'Rates' table)
Starthourweek 0 (Start hour in the week of this tariff)
Endhourweek 167 (End hour in the week of this tariff)
Penalty (Optional price added to this tariff)
Timezone GMT (Timezone, reflects the local time of the tariff)
Incr 1 (Used to consider the duration of the call in increments)
Min_Dur 1 (Minimum duration of the call)
Curr_code EUR (Currency used in iso format)
Carrier IN (Role of the subscriber, in this case the caller)

Linking rates to profiles

Rates include information used to calculate the price of a call. A rate can apply to several profiles. Go to 'Rates' in the 'Action' area and insert a new rate:

Reseller (automatically generated Id)
Rate PROFCLIENT (Link to profile in the 'Profiles' table)
Destination 34123 (Destination number to this rate)
Region (Optional region of this number)
Description (Optional description of the destination)
App audio (Application type)
Price 1 (Price per minute)
Start Date 2008-01-01 (Start time of the rate)
End Date 2022-01-01 (End time of the rate)
Blocked 0 (Blocked rate flag)
Billtime_sum (Automatically updated billed time of this rate)
Ringtime_sum (Automatically updated ring time)
Setuptime_sum (Automatically updated setup time)
Calls_count (Automatically updated number of calls)
Success_count (Automatically updated number of connected calls)
Acd_short (Automatically updated short-term average call duration)
Acd_avr (Automatically updated long-term average call duration)

Adding a DID subscriber

We are going to create a DID subscriber for a range of own numbers.

Adding a DID profile

Follow the previous explanation for linking a customer to a profile, only changing this fields:

Profile DID_OURS (Profile name. Links the customers in the 'Customer' table)
Rate DID_OURS (Link to profile's rates in the 'Rates' table)
Carrier DIDRANGE (Role of the subscriber. DIDRANGE is needed to define the range of your own numbers)

Setting up block of DID numbers

Follow the previous explanation for linking rates to profiles, and change this fields:

Rate DID_OURS (Link to profile in the 'Profiles' table)
Destination 34123 (Destination number to this rate. In this case this is the range of own numbers)
Price 0 (Price per minute)

Linking a DID to a client

Go to 'DIDclients' in the 'Action' area:

Reseller (Automatically generated Id of reseller)
DID_number 34123456113 (Number of the client)
DID_subscriber user3@domain.com (Subscriber who owns number)

Make a test call

Create an account for one of your customers in a softphone and verify it registers :
