AudioCodes MediaPack analog telephone adapters range from single-port models to 24-port models. The ATAs are compatible with standards such as SIP and T.38 fax. Onboard echo cancellation, jitter buffer and comfort noise generation produce a high-quality analog-to-VoIP (or VoIP-to-analog) experience.
The FXS ports connect analog phones and fax machines to your VoIP network. The FXO ports are built for PSTN and failover connections. Several AudioCodes ATAs are hybrid FXS and FXO models for combining purposes.
