AR 168M VoIP Module Feature
AR168M is a high integrated and low cost module based on the SOC AR1688. It can be through UART
(Universal Asynchronous Receiver/Transmitter) or SPI (Serial Peripheral Interface) connect to upper host.
It support SIP and IAX2 VOIP protocol and most popular CODEC algorithm and can meet various requirements
for different applications.
One can easily use AR168M to implement an IP phone without need to understand the complex technical details.
It will be helpful to shorten the time to market for most users.
Applications
IP Phone
Wi-Fi IP Phone
DECT Cordless IP Phone
PSTN/IP Dual mode Phone
IP Door Phone
Echo Cancellation Application
Active Noise Reduction Application
Voice Application For Embedded System
