linphone new 4

Linphone has reached a very useful level of functionality. It is a convenient and useful softphone. It is one of the most popular methods for accessing Voice over Internet Protocol and is a great and cost-effective way of communications.

Linphone was the first open source software that used the Session Initiation Protocol (SIP) with VoIP. This open source software has voice, video and messaging features that can be used with any SIP VoIP operator and can be distributed free. VoIP phones essentially transforms the telephone data that can be transmitted over the internet. Our previous blog post about Linphone explains about the advanced features of Linphone for various development platforms.

Linphone for Windows

Industry experts are killing the rumours that Microsoft is about to kill Windows phone. Contrary to the popular opinion, Windows phone is out in the battle. In various parts of the world, sales of Windows phone are rocketing past the iPhone.

Using Linphone on Android can be seen in common. But switching to Windows phone has got one more reason too, that Windows phone supports for a VoIP SIP client. Linphone for Windows 8.0 and 8.1 Phones appears a step in right direction. Downloading and installing Linphone for Windows phone is easy. It is easy to get Linphone and to register with voip.ms directly. But you will be able to receive incoming calls only when you use an account at Linphone.org.

Krify, being a professional mobile app development company, has developed Linphone apps for different platforms of mobile OS. Building a Linphone for Windows Phones is also one of the competency that our expert team of Linphone app developers has.

The settings and functionalities can be customised as per the app requirement.

This test application has been tested and is stable with sip.linphone.org domain and under testing phase for other sip domains. Therefore further scope for integrating and enhancing the features like that of contacts, where there is no option to add/create a new contact. It only lists the contacts from the address book whichever are visible. Also, it is difficult to integrate call functionality with audio codes like AMR-NB, AMR-WB, G722, ILBC, ISAC, SILK 16. Audio conference feature is also not supported by this version.
