feature a VoIP engine, WAN router, and Power over Ethernet LAN switch. The G350 provides
full support for legacy DCP and analog telephones. The G250 supports legacy analog
telephones, and the G250-DCP model also supports DCP telephones.
The G350 is designed for use in a 16-40 user environment, but can support sites with up to 72
