Voice over 3G
18.1 Overview
4G only supports all-IP-based packet-switched telephony services. When Voice over 3G (Vo3G) is
enabled, the LTE5366 supports Circuit Switched FallBack (CSFB) to deliver/receive circuit-switched voice
calls and text messages via a 2G/3G mobile network and then goes back to the 4G LTE network to
transmit data packets.
With Vo3G, users do not need a SIP account and SIP server to make phone calls over the Internet.
Note: You can enable either VoIP or Vo3G on the LTE5366, but not both at the same time.
