We are currently running a number of Cisco VoIP phones over Cat3 cable by locking the switch port at 10 Mbps. They're running half duplex and we haven't noted any problems.

Wrecking it out would be prohibitively expensive, but CAT3 isn't useful for much of anything these days. But would it be possible to use it for a VOIP phone system? I should be able to get 10MBps through it, and VOIP doesn't use more that 128KBps or so, right? _______________________________________________ Discuss mailing list Discuss@lopsa.org http://lopsa.org/cgi-bin/mailman/listinfo/discuss This list provided by the League of Professional System Administrators http://lopsa.org/
