We make use of the Owera AS SIP SDK in our applications and thus make no use of the Nokia SIP stack found on Symbian OS mobile phones. This allows us to port the application to other operating systems with ease and to make sure it is highly interoperable with the most popular soft-switches, proxies and servers found on the internet and inside the enterprise domain.

We maintain a generic version of a mobile VoIP application, which we call MVoIP, that we customise and further enhance for our clients.

Mobile phone software platform fragmentation is pervasive and we are well aware of it. In our case, MVoIP is compatible with most Nokia phones equipped with Wi-Fi running on Symbian OS and S60 3rd FP1, FP2 and S60v5.

Since we make use of the well-proven and highly interoperable Owera SIP stack, we are always on the cutting edge of VoIP developments. This mature stack has been deployed all over the world with the likes of AT&T, KPN, Telenor, Canal Digital, Telia and others.

Features

• MVoIP is simple to install, configure and run.
• MVoIP is always on thanks to auto-start, background run and auto-connect to network.

• MVoIP is highly integrated with the mobile handset and it can access contacts, handle GSM calls, control voice volume and mute.
• MVoIP offers high quality sound.
• MVoIP is energy efficient during calls and in standby mode.
• MVoIP can be always on thanks to its auto-start and auto-connect to network feature.

Usually clients (such as ITSPs and ISPs) apart from requiring their own GUI, they need to add features such as:

• Presence - It enables to view which of your colleagues/friends are online
• Security (call encryption)
• Viral marketing (invite all phone contacts to MVoIP)
• Multi party call (conf call)
• SMS/MMS integration
• Location sharing
• Instant Messaging
• Credit top-up integration
