More a network question, but that's my main job. Normally this should work, 5 phones don't generate a lot of traffic, especially when not in a call. But a few suggestions: You say you connected a hub, replace it by a small 8 port switch, if budget allows a managed one. - a hub is half-duplex shared, if one device sends the rest has to listen (walky talkie-style). - a switch is full duplex, not shared. One device can send and receive at the same time. - you can't really troubleshoot a hub
What's at the other end of the link, probably a switch. - what is the current port speed - what is the current duplex setting on the central switch port, to connect a hub all is good except fixed-full. - what/how many mac-addresses can you see on the central switch port How is the link - Test the same setup on another link, or better connect the hub directly to a central switch port IP-addressing - Is the DHCP range big enough - Connect a laptop as third device and look at IP-settings etc Best regards / Mit freundlichen Grüßen / Sincères salutations Paul Scheepens > ----- Message from "IT Services" <itservi...@apiwellness.org> on > Thu, 12 Nov 2009 13:10:22 -0800 ----- > > To: > > <sipx-users@list.sipfoundry.org> > > Subject: > > [sipx-users] Issue with connecting phones to 8-port hub > > Hi all: > > One of our offices has only one network drop available for the 5 phones > in that room.
