Description
This module encodes and decodes the SIP protocol and RTP audio stream from the network.
The module supports a variety of network protocols and audio codec protocols, and can be used for applications such as VoIP and IP
paging, and high-quality music streaming media play. At the same time.
SIP2703T also provides two serial ports, eight digital input/output, allowing users to control through programs.
SIP2703T is compatible with SIP2103T and SIP2403T, and supports GPIO and serial ports.
