EE is to introduce Wi-Fi calling capability, as it aims to further improve customer service levels.
According to the broadband provider, consumers will be able to make calls with a higher quality and greater degree of reliability than unmanaged VoIP services.
They will be able to use their home or office broadband, corporate network or public Wi-Fi connection, with no need to rely on an app.
EE is set to launch the Wi-Fi calling service in autumn 2014.
Fotis Karonis, Chief Technology Officer at EE, said the firm's Wi-Fi calling capability will allow customers to make calls where they have access to Wi-Fi but not to its mobile network.
"The customer experience is seamless because it’s the same as making a network call and uses the normal call interface of the handset," he stated.
"This is a major part of our strategy to invest in giving customers the ability to make a call wherever they are."
Mr Karonis said EE is confident that the service can make "a big difference" to people in homes and large offices across the country.
This will especially be the case in the most rural areas, where there is poor mobile coverage, he noted.
