SIP Intercom Help Module Supports Full-duplex Two-way Intercom 602T

SIP602T is a SIP network intercom module, which supports full-duplex two-way intercom, G.722, G.711A/U codec and MP3 audio decoding, and has a good echo suppression function. SIP602T also supports setting up to 10 multicast areas with priority, which can be used as a broadcast terminal.
  • SIP602T




SIP602T is a SIP network intercom module with 10/100M Ethernet interface. It receives audio data from SIP network, decodes and plays it in real time, and can be connected to microphone input and speaker output. The SIP602T module can realize SIP intercom, playback and other functions.

Installation And Configuration

SIP602T has RJ45 network interface and DC5.5-2.1 power interface, and also supports POE function. After power on, SIP602T will automatically obtain an IP address (BootP or DHCP), or use the Manager software to find its IP address. The terminal can also be easily configured and controlled via a standard web browser.

Application Development and Integration

SIP602T supports various control and communication modes, and we provide development documents and programming examples for playback and SIP intercom (out of SIP server). It also provides serial port control commands and network control commands. Software developers can write their own audio applications with custom functions.
