Yeastar TA2400 FXS Gateway with 24 Ports for Analog Phone and VoIP Integration

The Yeastar TA2400 is a high-capacity VoIP FXS gateway for organizations and operators managing up to 24 active analog terminals, providing 24 FXS ports through RJ11 interfaces and an RJ21 50-pin connector for connecting analog telephones and fax machines to enterprise-scale IP-PBX systems and VoIP infrastructure. A dedicated 10/100 Mbps WAN port, Remote Management, SNMP, and a 440×250×44 mm rack-mount chassis position the device for distributed infrastructure deployments and technical room installations. Supports SIP (RFC3261) and IAX2.

The TA2400 supports TLS and SRTP, voice codecs G.711 (alaw/ulaw), G.722, G.726, G.729A/B, GSM, and ADPCM, ITU-T G.168 LEC echo cancellation with Dynamic Jitter Buffer, VAD, CNG, and PLC.
