Landline to Mobile Call Charges Slashed to 4.5 ppm

The cost of calling mobile phones is now only 4.5 ppm with Westlake Communications new low cost business telephone call plan.

Traditionally the cost of calling mobiles has always been high, but recent regulation has caused a big price drop for business users that want to reduce the cost of calling mobile phones.  Until recently the average cost to call a mobile phone was around 8 ppm, so this new price is almost 50% cheaper.

Companies that have wanted to reduce their landline to mobile call charges were forced to use a GSM Gateway which was a piece of hardware that could be connected to a business telephone system and used a mobile phone SIM card to enable calls to be made using more competitive mobile to mobile call tariffs.  Using a GSM gateway could reduce business calls to mobiles to around 4 ppm so this new low call charge to mobile phones of only 4.5ppm makes the use of a GSM Gateway obsolete for call cost reduction.

GSM gateways are still widely used as alternatives to telephone lines for remote or temporary offices and also to propvide convenient telephone connectivity for applications such as alarms (lift alarms, care alarms etc) or for connection to a stand alone telephone for expample as part of a taxi phone solution.

Call charges to mobile phones are set to drop even further over the next two years with calls as low as 2 ppm in 2014.

Is your business prepared for the cold weather?

The annual freeze is upon the UK with forecasts of snow and freezing temperatures and of course the possible disruption to business inlcuding staff shortages as employees refuse to struggle through dangerous conditions to get to work.  In this age of high speed internet and multitude of communications options it should be easy for desk based employees to work from home and it is not as expensive as you might think as long as you have made some preperations.

The obvious first choice is using VoIP (Voice Over IP) so that home based employees, even temporarily snowed in ones, can communicate with the office and customers seamlessly.  As long as they have a reliable ADSL connection at home and a PC with suitable headset they can quickly establish a connection with the office phone system to remain a productive member of the team.  Even if your business does not have a VoIP or VoIP enabled telephone system you can plan ahead by installing a VoIP Gateway which will easily upgrade your existing phone system to provide basic VoIP connectivity as a backup for this type of situation.  The Telecom FM Onestream VoIP Gateway will connect to your small business phone system and provide VoIP connectivity for both the office phone system and also allow home workers to connect using an IP softphone on their computer or they could use an IP Phone at home and be able to answer incoming calls and transfer them back to the office.  The Onestream Gateway also fetures a built-in GSM Gateway so the company can reduce their call charges to mobile phones or provide easy, low cost mobile extension functionality for their mobile workforce.

The next thing that a home based employee will need to do is access their office PC and applications from their home computer and this is easily achieved using a basic VNC service or a paid for remote access solutions such as gotomypc or logmein which are easy to set up and allow the user to work as though sitting at their desk.

With a little planning, and maybe a small outlay for items like VoIP Gateways which can provide additional benefits such as reduced call charges throughout the year, most small businesses can easily survive the cold snap.


Using GSM Gateways on Vodafone

We were recently asked about the Vodafone policy about using Vodafone SIM cards with GSM gateways.  In the Vodafone contract and on their website they state :-

“GSM Gateway Commercial Policy


A GSM Gateway is any equipment containing a SIM card which enables the routing of calls from fixed apparatus to mobile equipment by establishing a mobile to mobile call.

In view of the uncertainty over the legality of certain types of GSM Gateways, Vodafone’s policy is not to accept applications for the operation of GSM Gateways on its network. Customers should be aware that where a GSM Gateway is connected to the Vodafone network in breach of this policy, Vodafone has and will continue to disconnect SIM cards that it believes are being used illegally.”

The above can be found at http://online.vodafone.co.uk/dispatch/Portal/appmanager/vodafone/wrp?_nfpb=true&_pageLabel=template12&pageID=TC_0032

This would suggest that Vodafone, apart from not being able to interpret some pretty basic legal ruling from Ofcom, will not under any circumstances accept or tolerate a Vodafone SIM card to be used in a device that will allow a fixed telephone device, such as a telephone to be used on their network.

If this is truly the case then why do they continue to offer the Vodafone B970 3G Router that contains a telephone port that you can connect a telephone and make voice calls – this is in fact acting as a GSM Gateway so any Vodafone SIM card used in this unit that has been used for a voice call should be terminated. 

Why are they also offering GSM Fax numbers becuase how else will a SIM card be able to receive faxes without the use of a GSM Fax Terminal that you can connect a fax machine to.  The same sort of single SIM GSM Gateway terminal used by thousands of companies with temporary or remote sites that rely on mobile phone communications.

I hope that Vodafone is able to provide some clarity as to their business policy as it does not make sense to us and many of their customers.

The Onestream Gateway has different models depending on your phone system type.  There is the Onestream GFX for analogue phone systems and the Onestrem GBRI2 and Onestream GBRI4 for ISDN2e phone systems and for businesses that have already upgraded to a VoIP phone system but want to make low cost calls using a GSM Gateway then the Onestream G is a VoIP GSM Gateway.


Fax over GSM is not a new concept, with the service being available in the UK since 1994.  The GSM Fax service really took off in the UK in 1996 when Nokia launched the Nokia 9000 Communicator, which enabled the user of this early smartphone to receive and view faxes on it’s LCD display.  The Nokia 9000 could also enable the user to type a fax and send it to a normal fax machine.

Since then the GSM Fax service offered by the mobile phone networks has not changed a great deal becuase it is such a bsic service offering – the only slight improvement has been the availability of GSM Fax Terminals such as the telecom FM Cellfax Plus.  A SIM Card is inserted into the Cellfax unit which then provides a connection to enable a standard analogue fax machine to be conected to enable faxes to be sent and received just like using a standard PSTN analogue telephone line.

This means tht temporary or mobile offices can still take advantage of the GSM Fax service offered by the mobile phone networks, providing convenience for when you really do need to send or receive a fax in this age of e-mail.  GSM Fax terminals are widely used by construction companies and are finding an increased use aboard ships and other marine work and pleasure craft.

Surge in popularity of GSM Gateways for small business users

GSM Gateways have seen a surge of popularity due to the increase of Mobile Extension.  Many new phone systems include Mobile Extension capability that enable inbound calls to the PBX to be routed out on another line to a mobile phone and enable the remote user to answer the call as well as provide the capability of transferring that call back to other PBX extensions. 

Normally this process would use a second ISDN line to call the mobile phone, which would mean high call charges to use the Mobile Extension Facility.  By using a suitable ISDN or VoIP GSM Gateway and a mobile Phone Plan that provides free calls between users on the same plan, these Mobile Extension Calls can be made free of charge.

For telephone systems that do not have Mobile Extension functionality built-in there are GSM Gateways available that can connect between the telephone system and the telephone lines and provide mobile extension functionality, wihout the expense of upgrading the whole telephone system. 

The Telecom FM Onestream is a great example of  a GSM Mobile Extension Gateway providing mobile extension functionality for analogue and ISDN2 phone systems as well as providing the additional benefit of having a built in VoIP Gateway to enable the same Analogue or ISDN2 telephone system to make calls using a VoIP Telephone provider (SIP Trunk).
