VOIP on Droid 4
I'm planning on traveling to puerto rico and verizon has been inconsistent enough with how they describe their charges/coverage that i want to have a voip backup on my D4. I recall that Gingerbread is supposed to have integrated VOIP calling, but I can't find it! i've looked all over. any ideas where it's hiding on 2.3.6??
Barring that, any suggestions on the best SIP client to use? My provider is callcentric.
I'm pretty sure the built in VoIP is in ICS, not Gingerbread.
