Read the story →Bridge analog and digital networks with IP telephony for maximum cost efficiency and operation flexibility — TA Series FXS/FXO and TE Series E1/T1/PRI gateways.
A VoIP gateway is a hardware device that converts telephony traffic into packets of data for transmission over the internet, bridging analog, digital and IP networks. Depending on where the voice signal originates, the gateway converts it into the correct form for the destination network.
If the voice signal originates from the PSTN, a VoIP gateway converts the analog signal into data packets and sends it to the IP-based phone system — and vice versa.
A VoIP gateway also converts digital landline signals into data packets, allowing the two networks to communicate.
Three gateway families for analog FXS, analog FXO and digital E1/T1/PRI connectivity.

Connects legacy phones, fax machines and phone systems with IP telephony networks and IP-based phone systems. Models: TA400, TA800, TA1600, TA2400 and TA3200.

Beyond preserving current investments, VoIP gateways let you enjoy free internal calls and flexible call routing over the internet — maximizing limited budgets and cutting telephony charges and operational costs.
Yeastar VoIP Gateways come with a user-friendly web interface, intuitive operation and simple installation. The TA Series also supports auto-provisioning with Yeastar IP-PBX, minimizing configuration hassle for IT admins.
Connect legacy phones and fax machines to the FXS ports of TA Series gateways or analog telephony adapters so they work as extensions of the IP-PBX. Ideal for hotels keeping existing analog phones alongside an IP phone system.
