Well, you might in that difficult position where your existing phone system is no longer supported by the people initially made it or, HAPPY NEWS, your office is expanding but bad news, your existing PBX reached its maximum capacity. In both cases, you will be looking for a new PBX system. Everyone around you talks only about how everything is getting to the cloud and goes virtual, in a digitized form or another… including your phone! Hmm, for starters, that old beige phone might not be compatible with the new PBX if it is not talking IP protocol, like any other “Thing” around you, including the fridge, the car, the security video-camera, the TV, the thermostat, the door, the garage door, you name it…
So, you start looking on the web pages of the service providers, you talk to couple of friends that have comparable businesses with yours to have an idea of possible solutions. You will see some of them want full control of their systems, they already have the network and cabling infrastructure, thus they buy the new IP PBX system and install it in their existing data center. Some others, will not want to invest upfront in any network infrastructure and would rather pay a price per phone per month and let somebody else to take care of the voice communication system maintenance.
Question is the cost for a user per month? The lines below will give an example for the cost components. You can take this as a negotiation starting point with the sales person in front of you, like having an idea of the dealer invoice price when you shop for a new car…
An existing office with 30 people needs a new ON-SITE IP PBX system. The old PBX is already connected to PSTN using 8 analog lines (1FL). The existing phones cannot be reused for the new system.
The office already has the required network infrastructure to support the implementation of the new IP PBX:
- CAT5E cabling for each an every place a new IP phone will be installed. If a cable is already in place for the User’s PC, the Phone will use the same cable for the network connectivity, too.
- Network switch ports with Power Over Ethernet capabilities. One port per phone is required, since the phone is powered on via the network cabling by the network switch
- Internet Connectivity terminated with statefull firewall. This will be required for the new PSTN connectivity using the SIP protocol. One Mbps traffic in both upstream and downstream directions will be added by the PSTN voice connectivity.
- OPTIONAL – an UPS will power all the network components and the IP PBX system components for an unwanted power failure up to 30 min.
Solution proposal and components
The proposed solution is based on the commercial version of the well-known ASTERISK platform called FREEPBX has the following components:
- The FREEPBX system software comes installed on a dedicated appliance which has a capacity of maximum 60 users, so in our case a future growth of 100% is possible by simply adding phones ( no associated additional licensing costs). https://www.sangoma.com/wp-content/uploads/2016/03/Sangoma_DataSheet_PBXact_60.pdf
- A Session Border Controller with a capacity of 10 concurrent PSTN calls using SIP protocol. https://www.sangoma.com/wp-content/uploads/2016/06/SBC-SMB-Datasheet-web.pdf
- 30 new IP phones Sangoma S 500 https://www.sangoma.com/wp-content/uploads/2016/01/Sangoma_DataSheet_Phone-S500.pdf
- Migration of 8 existing PSTN phone lines to SIP connectivity while maintain the existing phone number
- Installation and configuration of 30 extensions/phones, one per user. The existing dialing plans will be maintained. Includes voicemail initial definition. Voice messages will not be migrated from the old system to the new one
- Configuration of one auto attendant, that includes dial by extension.
- One hour receptionist training.

The cost is calculated per user per month, supposing a period of 36 months usage.
For this example, we do get around 17 CAD per user per phone per month.
During the 36 months, two software updates for the PBX system and the phones will be performed.
The management of the system and ordinary changes (MACD) for the system configuration are estimated at 30 min per day, for an already existent network technician on-site and on staff.
