Pin Type SIP Protocol Intercom Module Board with Transparent Transmission Function

The SIP2703V network audio module is a general- purpose stand-alone SIP audio function module that can be easily embedded into OEM products. This module encodes and decodes SIP protocol and rtp audio stream from the network.
  • SIP2703V

  • SINREY

Availability:


SIP2703V 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


Features


• Standard RJ45 network interface, providing firmware online remote upgrade;

• Based on ARM + DSP architecture, high-speed industrial chip is adopted, with startup time ≤ 1s;

• Provide multiple IO interfaces and enrich module functions;

• It has the function of controlling serial port and can control the work of the module;

• It has the general serial port function and can realize the transparent data transmission function;

• It has an audio line output port, which can be externally connected to an active speaker for sound amplification;
