    I'm looking for someone to develop me an Android app that acts as a ""SIP server / mobile gateway" and makes the cellular line of the smartphone usable with a SIP client. So it is also a kind of VOIP mobile gateway. It may be possible to port the free IP telephony software to use the cell phone as a cellular gateway. However, it is important that the APP serves both as a gateway and as a SIP server, so you can log on to the app with any VOIP client to make calls via the smartphone's cellular network using SIP protocol (IP telephony). Important: The app should run on any modern Android smartphone running Android 10 or later.

    Linphone ASTPP integration -- 3 2 dias left
    VERIFICADO

    Hi, I am getting the source code for an ongoing project. The ASTPP switch already has API's built for the Linphone. The linphone code is pointing to an old switch. Step one: I just need the linphone to be migrated to a new switch. Step 2: 1. Bundle/Packages and DID -users can choose from —#different bundled minutes(ie. 80 mins to destination X & Y for $5, valid for Z amount of days.), ---#unlimited plans to certain destinations* —#user can buy DID (DID will show as caller ID for that user) 2. Caller ID For regulatory reasons, we can't modify the caller ID to be that of another local provider.. -when users call from the App, it need to show caller ID unavailable (until that person pays for a DID, or a bundle that includes a DID.) -Then when the ca...
