GrandStream GS-GXW4248 48 Port FXS Gateway

For businesses that need dependable connections for as many as 48 analogue phones or fax machines, the Grandstream GXW4248 v2 is a high-density analogue VoIP gateway. It provides 48 FXS ports alongside 2 Gigabit Ethernet ports and can handle up to 30 simultaneous SIP calls, which makes it well suited to medium and large offices, hotels or call centres. A broad selection of voice codecs is supported, including G.711, G.729A/B, G.722, iLBC and GSM, so clear audio is maintained under different network conditions.

Security features prominently, with TLS, SRTP, HTTPS, SSH and 802.1X authentication helping to shield voice traffic from interception and unauthorised entry. Deployment and management are made easier by provisioning through TR-069, XML, TFTP/HTTP/HTTPS or configuration files. The 1U rack-mountable unit (440 x 220 x 44 mm) suits standard server racks, and its power supply takes a 100-240V AC input and delivers a 12V DC output.
