Here is the link to a video I've just uploaded that shows how to use the new VoIP (rx/tx audio) feature in the upcoming CommCat Mobile 2.1 and CommCat 4.5.

These new versions are on the way. I'll post here as they are released.

As you will see, using the new VoIP feature is a snap. Tap a button in CommCat Mobile on your iPhone or iPad, to connect instantly to the rx/tx audio on your radio. Skype will continue to be supported, but it isn't nearly as handy to use. CommCat VoIP requires CommCat Mobile 2.1 or later, CommCat 4.5 or later, and a CommCat Live account.
