ICE Clients allow you to make and receive VoIP telephony calls that are connected via the IP network and do not utilize the cellular phone plan. If your ICE Server is also configured for access to the public telephone network (PSTN), then you can make calls to public phone numbers.

Telephone calls are full duplex by default and do not utilize the PTT button unless Telephony as a Channel is enabled in Settings.

IMPORTANT: You can always initiate private calls with other ICE Mobile users; however, a telephony-enabled profile is only required to access the public telephone system (PSTN).
