The number of Voice over LTE (VoLTE) connections will exceed one billion by 2018 and two billion by 2020 a recent study from Juniper Research concluded. This projected number of active VoLTE connections compares with an estimated 123 million connections currently.

The report concludes that the Far East and China will account for over 50 percent of the global VoLTE connections in five years’ time.

According to figures from the Global mobile Suppliers Association (GSA), 25 operators in 16 countries have launched VoLTE services as of July this year.

PTT’s online course MBG: “LTE mobile systems” includes an explanation of the operation and benefits of VoLTE while MOF: “LTE (4G) mobile radio networks” introduces the principles and features of LTE.

Those who are in a customer facing role in the telecoms sector know the headline features of the services they are selling. But do they have sufficient grasp of the wider picture to guide potential customers and help those reporting faults?

Instilling customers with the confidence they are receiving impartial and accurate information is an important step to brand loyalty.

PTT’s new online course “Introduction to telecoms services” is aimed at customer service agents and retail sales representatives working in the telecoms sector. This course introduces the facilities and capabilities of modern telephony, broadband, and mobile services.

The course uses interactivity to fully involve the learner and does not assume any prior knowledge of telecoms.

There are two versions of this course, one designed for access on a PC or laptop, the other designed for access on a tablet. So staff can study at the office, at home or on the train, whenever they have a few spare minutes.

Telecoms service providers and businesses are increasingly relying on a single type of network to provide all services including telephony and video conferencing.

The PTT online course which provides a comprehensive introduction to “Voice over IP” (VoIP) has recently been updated to reflect the latest developments in the technology. Apart from introducing VoIP principles and protocols, the course MAB: “Voice over IP” reviews the use of VoIP for fixed line and mobile telephony services.
