This quick start guide covers basic steps from installing sipXcom to placing internal and external calls.  Whether you are installing thousands of phones or just setting up a demo system, sipXcom graphical user interface makes the process straightforward and easy.


For large and complex installations, sipXcom provides high reliability, rich functionality, significant reductions in capital expenses (CAPEX) and significant reductions in operating expenses (OPEX). CAPEX is reduced by cost-effective features such as sipXcom running on standard Intel and and AMD servers under open-source Linux and the freedom to competitively purchase hard and soft phonessoftphones, gateways, switches, etc. from many different manufacturers and vendors. OPEX is reduced by the ability to auto-provision phones, centrally administer the system, ease of use and least cost routing.

To get started exploring sipXcom, you can set up an almost free demo sipXcom system. A public cloud installation for demo and testing can be set up for about $20 per month. A domain can be acquired for as little as $1 for one year. SIP trunking can be set up for $1 per month for a DID telephone number and 1c per minute for incoming and outgoing calls in the USA. Softphones such as LINPHONE are open source and free. Other low-cost options are to install sipXcom on open source VirtualBox or an existing CentOS server.


  1. Create DNS records for your domainCreate ISO DVD and boot from ISO DVD

  2. Install CentOS 7

    1. Enter network settings

    2. Enter host and domain settings

  3. Update Install sipXcom with maintenance releases

  4. Select Configure server core, telephony, and device services

  5. Add Users

  6. Configure soft and or hard phones

  7. Add SIP Trunking for incoming and outgoing telephone calls

DNS Records for Your Domain

sipXcom requires correct DNS settings to work. And it requires that your PC's (if you want to run softphones) and SIP devices have DNS working properly. It can automatically configure its own DNS server or tell you what the settings need to be. To only test the admin UI, you don't need DNS setup and can use the IP address, but it is still good to at least have the A record for the host set.


A DNS Domain that is equivalent to the SIP domain
A-Record (host record) for the server
SRV records for the SIP communications (port 5060 tcp & udp).
SRV record for the resource record (port 5070 tcp)
SRV record for XMPP client connections (port 5222 tcp)
SRV record for XMPP server connections (port 5269 tcp)
SRV record for XMPP client connections to XMPP conference (port 5222)
SRV record for XMPP servers connections to XMPP conference (port 5222)

Please follow the guidance in the link below:

Obtain, Burn and Boot CentOS 7 Minimal Installation



Download a stable release or development CentOS 7 ISO from here, burn the image on a physical DVD. The ISO contains CentOS Linux operating system and sipXcom and all related compenents.

WARNING: The installation will delete ALL data on ALL drives connected to the system. REALLY, IT WILL! It will format the hard drives, create its own partitions and the process will start as soon as you hit Enter. Make sure that you know what you are doing.

Insert the DVD into your Intel or AMD server and power it up.

Network Settings

Log in to the system as root with the password you provided earlier and continue to configure sipXcom starting with Network Settings. Enter "n" response to "Would you like to configure your system's network settings?" and continue entering the rest of the items.

Set superadmin password

Using a computer with network connectivity to the newly installed server, launch a Web browser and go to the URL or IP address displayed by the setup wizard (just the hostname of your server).

Note: Some browsers are disallowing self-signed certificates (IE and Chrome).  Try using FireFox and adding in the self-signed certificate as trusted to get by.  Then get a certificate added as soon as possible.  See: Certificates

You may get a certificate warning as seen below (browser dependent... for Chrome click and then click 'Proceed to XXXXXX (unsafe)'):


  • The first time you log in Configuration Server Web UI you have to set superadmin's password (enter a strong (hard-to-guess) password that you will not forget)

Log in Configuration Server Web UI

Use superadmin for User ID and password set in the step before for logging in Web UI.

Update DNS external servers

Insert one or more external DNS servers that can resolve external names (System Menu -> DNS).

Update sipXcom with maintenance releases

Logout of the Admin Portal. Then sign in to sipXcom server as root.


Guidance on upgrading can be found at:

Configure Servers – Core Services

Log into Admin Portal. Select all the services checked and Apply. You can mouse over the services for a description of each service.


An easy approach is to enable DHCP services and place the phones on a dedicated network segment separate from installed data devices (and other DHCP services).

Configure Servers – Telephony Services

Select all the services checked and Apply. You can mouse over the services for a description of each service.

Configuring Servers - Instant Messaging

Select all and Apply.

Configure Servers – Device Provisioning

Select options checked and Apply. You can mouse over the services for a description of each service.

Add Users

Click Users -> Users and then "Add New User"

User ID is automatically inserted but may be changed. At a minimum, check Enabled and enter Last Name, First Name, for user portal Password, and password for Voicemail. SIP password is automatically generated but may be changed. Check Apply and OK.


In either case, if a phone is not configured by sipXcom then it does NOT need a phone entry (as in the example of LINPHONE below)

Softphone Configuration

An open source SIP soft phone, softphone, such as Jitsi or LINPHONE for Windows, MAC OSX and Linux can be used.

LINPHONE can be downloaded from:

LINPHONE is also available at no cost for:
Mobile Devices – Android, iOS and Windows 8 from Appstore and Google Play
Web Browsers - Chrome, Internet Explorer, Mozilla Firefox and Safari @


Configure your account and click Apply. Your LINPHONE will register on sipXcom and you are ready to make calls between extensions.
Username: must be a User ID already set up on sipXcom
Password: SIP Password for the above Username from sipXcom Advanced Settings on User Identification screen
Domain: Fully Qualified Domain Name (host plus domain) or use Domain name if you have SIP SRV records in the DNS zone.

Use Dialer to Make Calls

At the bottom of the screen, please see "Registration on successful."


Dialer reflects call in progress.

Hard Phone Configuration

  • Navigate to Devices > Phones

ADD New Phone  

sipXcom will automatically configure the many brands and models of hard phones shown in the drop down list shown on the next page. Information on phones can be found in the Wiki at

To automatically configure phones, Server Configuration – Device Provisioning must be set up. Just plug in a supported phone to the VOIP network or VLAN that sipXcom resides on and sipXcom will automatically configure the phone.

Polycom phones will self configure when plugged into the sipXcom system network. The Cisco Discovery Protocol is used. The phone will initially configure with an unique extension ID displayed on the phone such as W9B. The new phone will be listed with the unique ID in the description under Devices, Phones. At this point, you can add lines to this phone, save and send profiles. The phone will re-boot and display the lines added. Please also see

The alternative to the automatic configuration is manual configuration described next.


Insert the serial number of the phone which is the MAC address. Also, select the most current firmware version available on sipXcom for this model of phone.

Click OK. 

Add New Lines

  • After creating the phone navigate to User Lines tab and Add New Line


Perform the same steps for the second user - add new phone and assign user 201. 

Send Profiles

After creating the phones and assigning lines you have to send profiles to phones for the settings to become effective in the phones. In the phone main page select the phones and click Send Profiles button. Monitor status of action in Diagnostics > Job Status page.


  • After sending profiles the phones will reboot and you can place a call from extension 200 to 201.


SIP Trunking is one way to provide the capability to connect to the Public Switched Telephone Network (PSTN). This will allow you to make a call to someone on the PSTN and to receive calls from others connected to the PSTN.   

Setup Gateway Configuration


Contact an Interoperable ITSP provider to get account information and ITSP server information from list at:

Select Devices - Gateways - Add New Gateway - SIP Trunk
