With 4 FXS ports, it acts as the interface between the analog world and your VoIP infrastructure — registering each port as a SIP extension on your PBX and presenting a standard phone jack to the connected device. Analog handsets, fax machines, DECT bases, and modems all plug in and function as if still connected to a traditional phone line.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 13px 0;\"\u003eRunning Cisco IOS Voice, the VG204 supports dial plan configuration, codec selection (G.711, G.729), DTMF relay, and call progress tone generation for Australian PSTN compatibility. T.38 fax relay handles fax-over-IP transmission reliably — a common pain point with VoIP gateways that use G.711 pass-through only. Integration with Cisco Unified Communications Manager Express (CME) or CUCM allows the gateway to be managed within the broader Cisco UC framework.\u003c\/p\u003e\n\u003cp style=\"margin:0 0 20px 0;\"\u003eFor small offices with a mix of IP phones and legacy analog devices, the VG204 eliminates the need to maintain a separate PSTN connection solely for fax or a few analog handsets. Branch offices in a hub-and-spoke UC deployment can use it to provide local analog extensions without separate PBX hardware at each site.\u003c\/p\u003e\n\u003ch2

(on the VG204) connect to analog phones and fax machines — the gateway provides dial tone and ring voltage.
