PSTN Trunking for IP-PBX
TA FXO Gateway provides an easy and trustworthy conjunction of IP-based system and traditional telephone line. It is suitable when the local IP telephony network is constructed gradually in an institution that already has a legacy telephony network. Any SIP-based VoIP infrastructure, including IP-PBX, hosted IP-PBX, VoIP call center could benefit from this conjunction.

Analog Extensions for IP-PBX
By connecting analog phones and fax machines directly to the FXS ports of TA series gateways, or TA series analog telephony adapters, analog phones are enabled to work as extensions of the IP-PBX. Without additional investment on expensive IP phones, enterprises could access VoIP networks with the cheap analog phones.
