Yeastar N824 Smart Analog Phone System
The Yeastar N824 is a hybrid analog-IP PBX built for small and medium businesses that already have existing analog phone lines and extensions but want to add SIP-based VoIP capability without a full system overhaul. It comes with 8 fixed FXO ports for connecting to traditional CO (central office) phone lines and 24 fixed FXS ports for analog handsets and fax machines — no extra expansion modules required. On the IP side, it supports up to 8 SIP extensions and 8 SIP trunks, along with up to 16 concurrent calls. The system includes a full suite of business telephony features — auto attendant (IVR), call queues, ring groups, call recording, voicemail-to-email, and time condition routing — making it a practical bridge for offices transitioning from legacy telephony toward VoIP.
