    home server - the harder way, depends on your technical specification. What functionality do you need from the server? For example Asterisk has audio-mixer for conference call, while it lacks user-presence (you need to integrate with Openfire). Kamailio/Openser support presence through SIMPLE, but they lack audio-mixer support (you need to integrate with Asterisk or SEMS). You can also consider "all-in" appliance like Sipwise, but it requires extensive knowledge if you want to configure something aside from the default configuration.

    The good part is, most of the servers require very little effort to get the sip audio calls running, so if you only need that, better is to setup your own server.

    The pros of this approach - you have total control over the service, you can view backend logs, you can test use-cases, which you can't with public service. The cons - it requires significant resource to setup, configure and support. This is subjective and depends on the functionality you need from the server.

    You can convert your voice to stream, then send it by WifiP2P, here is a similar demo.
