What is a SoftSwitch?

Having passed from live operators to automated hardware devices, most telephony switches introduced today are in effect central devices in a telecommunications network using software on open standards hardware. These voip switches have greatly reduced cost and increased functionality to an extent that we are only beginning to know & understand.

In many parts of the world, it is now typical that the connections made by the soft switch are done via the internet from one IP Telephony line to another, with even the media stream able to pass directly rather than the expense of bandwidth and resource staying on-net. There is, however, still the need to be able to interface with traditional hardware based switches and to have a true control of services, Media Stream must be controlled.

Class 4 Soft switches (Tandem) are used between local offices exchanges and carriers or carrier to carrier to avoid the high costs of long-distance calls via PSTN. Class 5 Soft switches, on the other hand, can route even PSTN telephone calls, making them an ideal solution to offer End Users. However, because of the interaction with the end users, Class 5 inevitably has the features and functions of a PBX which are increasingly a part of Unified Communications.


Soft switches are highly favorable to more traditional methods of routing for a number of reasons, including:
    voip soft switch
  • Higher scalability
  • Less hardware needed, saving money and space
  • Expansions or upgrades only involve new software, not a whole new product
  • More affordable
  • Open Standards creation, resulting in a more customized and flexible system
  • Remote installation is possible
  • Can route any & all types of incoming calls – IP, cable, copper, etc.
  • May provide extra software-based features such as:
    • Voicemail
    • Call recording
    • Billing
  • Requires less time-invested
Don’t waste time and resources with older, less efficient systems. Upgrade to a voip switch today and begin offering the above features – and more – to your customers!


So you’ve decided that you want to upgrade to a voip soft switch, but are unsure where to start. With so many options on the market, it’s important to do research and know what to look for. We’ll help you get started. When shopping for a voip switch, keep the following features in mind:

voip softswitchLEAST-COST ROUTING

Least-Cost Routing (LCR) is a feature that allows the soft switch to select and route to the least expensive outbound line of communication. The voip soft switch will periodically compare paths from different carriers and choose the least expensive one. This is especially useful if you or end users call a number of different companies. The least-cost route to a city in South America may be entirely different from the least-cost route to a city in India. With this feature, your voip switch will always route you to the least expensive route for that particular call.


There are a few ways to measure call capacity. It is important to ask about these measures and soft switch capacity when doing your shopping.

voip soft switchBusy Hour Call Attempts (BHCA) is a measurement of the number of attempted calls during the peak – busiest – hour. If the softswitch capacity does not meet or exceed the BHCA, you can expect failed calls and stress on the network. A good softswitch company will calculate their BHCA and adjust the capacity of the softswitch accordingly.

Similarly, the number of calls set up per second will give you an idea of how many incoming and outgoing calls you can have at once. Be sure to choose a softswitch that can handle the volume of calls you need. The number of simultaneous calls is another important angle to look at.

On the more technical side, the number of lines, racks, and media gateways is another measure of capacity. Again, do not make the mistake of selecting a softswitch with a capacity lower than what you need. In order for customer and your own satisfaction, the softswitch should have a capacity above and beyond what you need.


While some softswitches only include the barebones routing system, others come with incredibly useful features or add-ons. It is highly recommended to take advantage of those features. Look for a softswitch that can integrate with other modules and essentially serves as a central controller. Some useful add-ons include:
    voip softswitch
  • SIP PROXY - A SIP Proxy is an indispensable softswitch feature that will allow routing of not only IP telephony calls but also traditional PSTN calls. If you wish to use your softswitch with end users, this feature is required.
  • PRESENCE SERVERS - A Presence Server feature will allow enhanced communication between users. It gathers information about connectivity and availability, giving users alternative ways to communicate. With this feature you will be able to select what to share and with whom.
  • BILLING - A softswitch with an included billing feature will save you ample time, money, and resources. It will automatically bill users based on calls. If you don’t want to look for and spend on separate billing software, look for a softswitch that includes a billing module or add-on.
  • REPORT GENERATION - Similarly, softswitches may include a report generation module that will automatically provide you with statistics about calls. Rather than buying software or paying additional employees to determine and report call statistics, look for a softswitch that will do this for you.

Finally, be sure to select a softswitch that is customizable and flexible. In today’s market, finding an open source option should not be difficult. This will allow you to customize the softswitch to your needs and those of your end users. Save money and time by getting a solution made just for you.

Definition of PBX Phone System

A PRIVATE BRANCH EXCHANGE (PBX) PHONE SYSTEM is an internal telephony network that allows for inexpensive calls within a company or organization. It is an efficient form of unifying communications within an office or network of branches. The PBX connects the private network to the Public Switched Telephone network (PSTN) for external calls. Specific outgoing lines are reserved for those calls.

Hosted PBX vs Google Voice vs On Premise PBX response

After reading Ruben on VoIP's article Hosted PBX vs Google Voice vs on premise PBX, I knew I had to write a response.

My first thought: Interesting and provocative in all the best senses. Oh the benefit though with hindsight.

Your ascertain that everything that can be done onsite can be done hosted is true. Your assumption that 'there are no reason why hosted PBXes can't have the same feature set as on premise PBX,' seems well … how can I put this ? "Academic." From being involved in the great efforts needed to see such ideas become reality here's a little insight to why simple writings and commentaries may not always suddenly see flows of actions.

For our part at Bicom Systems we started in 2003 at a point that this all seemed quite obvious. It took us until 2007 to start supplying hosted systems and we are just about to deploy with NEC a system for 50,000 business subscribers. I can give you two very big reasons why this statement does not have the reality to support it that may seem technically obvious.

The first reason is this : somebody has to do it. Who ? NEC, Siemens, Avaya, Mitel ? None of the incumbents are going to vote for Christmas.
Only Siemens have I seen begin to promote such a product through existing distribution channels and even then Siemens dealers that are twenty years in the business are not hesitating for a moment to move to PBXware. Simply - it does not have the features. NEC in the United States has put something together but again it lacks features.
Specificly - it does not have the features that 'the next customer'
requires. Yes - you read that right.

Each customer requires something unique. Mostly that can be achieved by configurations that the vendor can quickly convey to the dealer. Often though it needs development that comes about only by years of being in the market with each and every possible scenario and even that is only enough to allow you the space to be able to fulfill that next requirement..

What about Google ? Well - clearly they have not done much since your writing in 2009. Even if starting from a greenfield position in terms of market they wish to enter, the complexity of these small features that make the difference is not easy for a streamlined web site company to detail, never mind explain. This then brings me onto the second problem
- who is going to explain. From our experience the complexities are so great that only really the manufacturer truly understands once you get into the 'what if'. Resellers take weeks to gain a deliverable competency and years to gain reasonable competency. A new End User - just wants a phone systems up and working. There is a size of company that is 'just big enough' to have its own inside Network Support staff but not so big as to measure their worth in terms high enough that they would prefer to use more expert labour of 'a phone guy'. Yes we know the Network Support staff wants to play with new toys - but … you get my point by now ?

Broadsoft seems to have tried following its IPO and is doubtless under pressure to now pay dividends instead of investing its future. Sysmaster ? A long time since I heard the name and they never really got into the detail of SMBs.

Surely then with all the opening up of Open Source Telephony Systems there's someone out there that has the greenfield advantage that they are willing to disrupt the existing status quo but a wish to dedicate the time to detail, training and support of such complexity ?

There are certainly many out there. Which have the resource to take this forward ? Fonatliy seems spent. Digium seems still in search of a product for all that it has slaved with SWITCHvox I do hear a real uptake on the ground nor does the company seem overly open to resellers.

Finally here I am not saying you are wrong, we do believe in this cause and are working to it more quickly than many. It will though - Take Time!

At Bicom Systems we continue to make good on the advantages that we had secured since our outset of being involved in both onsite and hosted. We are though to invest heavily in producing the content of documentation and videos needed to support the using of such complicated tasks. Above all support needs to be as open as possible. The manner by which we will do this is known and being prepared but you'll just have to be patient to discover.

Multi-Tenant PBX

I'd like to take a few minutes today to shine the spotlight on one of our favorite suites here at Bicom Systems. We love talking about how to use our trio of products - SERVERware, TELCOware, and PBXware - to start & run an ITSP, but what about the individual products and editions?

Virtual Machine Technologies

I recently received this about using Amazon EC2:

"Here's what I'm finding... When a backup is made of the AWS instance (create AMI from instance), logging in immediately after the AMI is created will show all settings gone. Went out to the shell to look at the database, and it too was empty (except the default 1000 extension and multi-tenant PBXware default settings).

Restarting the system from the GUI, then logging in when it's back up will show all the settings back where they belong. Didn't do anything with licensing.

Then I did some backups, except didn't log in immediately when it was done. Waited 20 minutes to log in, and all the settings were there.

So it's something with the timing of how the machine instance comes up."

Conclusion : there are real problems using Virtual Machine Technologies and one must wonder about VMware too ?

Plantronics Malfunction

For the past four days my life has seemed on the edge of a cusp.

Having got habitually accustomed to our new Glocom 3.0 working off our MultiTenant PBXware and working off the SIP client on the desktop with perfect voice quality - my $350 headset just disappeared. Not from the desk beside me but neither the Mac nor a PC I borrowed could recognise it anymore. Torment and ridicule followed.

Pulling USBs in and out of my monitor, laptop 1, laptop 2 and even the coffee warmer at one point, tried to find drivers knowing well that I'd throw the CDs away - this though was an endless task as are no drivers for the device. Almost burst to complaint to their head office secretary as she was kindly setting up a meeting for a site visit by two of their staff to assist Denis with further integration. Just as well I bit my tongue at that moment!

The only pleasure was that to be had by smirking colleagues - 'mine works!'

Bugged the dear lady at in technical support but refused her RMA muttered for another day and then did the sensible thing and gave up and surrendered. Printed the RMA form, disconnected the USB CB60 from the power and sulked towards the printer to pick up the RMA form.

In a last fit of madness I connected the USB of a device that did not have any power coming to it - to the MAC and ... you know the rest ...

the Fairy Lights of the Plantronic's device started flashing - all was working.

The moral of the story - whenever there is anything technical not working - start by shooting the fairies. (Then try disconnecting the power cable and re-inserting it).
