Zello uses proprietary low-latency push-to-talk protocol and is not interoperable with Voxer, Sprint Direct Connect or AT&T Enhanced PTT. Zello Android client supports free public service, ZelloWork cloud service, and private Zello Enterprise Server. We are working hard to improve the app so please expect frequent updates.
