BT OnePhone Mobile Application vs R4Telecom mobile access

BT One Phone brings your fixed lines, mobile phones and phone system together, into a single hosted service that has flexibility at its heart. That means your customers can call your office or mobile number and get through to you on your mobile phone. The BT One Phone Application allows you to control your BT One Phone service when and where you want. My Status shows you your current presence status, number of new and saved voicemail messages, your last 3 calls and other useful information depending on the privileges for your user account. Presence status can be updated while on the move The company directory can be viewed and used to automatically call colleagues and see their presence status, or whether they are busy on another call. The company directory in the app is available also in an off-line mode. Local directory sync downloads the company directory into a separate contact group locally in your mobile phone. This makes it easy to call colleagues from your contacts and incoming calls also show the name of the colleague calling you. “Follow-me” lets you easily redirect all your incoming calls to a different number

The R4Telecom mobile access for iPhone works in conjunction with the BT One Voice service as available through BT Global. In order to use the application the end user must be registered with BT.  This application routes outgoing international calls to a BT One Voice gateway of the country where the call is made. The gateway will connect the call through via the managed BT network. Usage of the app will deliver cost savings for the customer. It should be noted that the app should be used within a country where the SIM card is registered
