Abstract: Techniques for multiple call types for a call event are described and may be implemented via a wireless device to enable multiple connections for wireless calls. For instance, redundant connections for a call event of a wireless device are established via different call types and utilized to exchange call media of the call event.

Thus, techniques for multiple call types for a call event are applicable to increase call quality in different scenarios and environments, such as in situations where a primary call connection experiences an anomaly condition that causes quality call degradation.
