A client (roughly 30 people) wants to replace their existing analog phone system with VoIP. However:

  • they have dual Ethernet drops to some desks, but not all
  • their (recently purchased) router does not support 802.1Q VLANs
  • their (recently purchased) core switch is layer 2 only

Is there any viable, reasonable solution that would allow them to:

  • avoid replacing router or switch
  • avoid running new Ethernet drops

Decent VOIP phones?

Starts with that:

  • A decent VOIP phone has a passtrhough switch. Come in on the phone, go out to the computer. The phone also gets powered by Ethernet - which is the point throwing the stupid switches they bought out and tell the uy that bought them he should take a job at McDonalds serving burgers.

  • Alternatively buy cheap small desktop switch is always an option.

  • 802.1Q VLANs is not really needed at all, you know, unless it is needed for other reasons, but nothing DEMANDS voip traffic to be on a VLAN.

Power over ethernet surely? Or if you where to get electricity via IPv4 can you point to me a server? ;) – symcbean Jul 6 '12 at 13:45
Ethernet, yes ;) Ipv4 - sure. I heary your computer can pull a lot from ;) Just make sure that server is on first ;) – TomTom Jul 6 '12 at 13:47
Most of those phones also allow you to buy power bricks as well so you don't have to use PoE – Brent Pabst Jul 6 '12 at 14:03
+1 for 802.1q, best 'fix' it up now, rather then messing with it in the future if demands increases with QOS. – Cold T Jul 6 '12 at 14:13
Actually you can do QOS without VLAN. VLAN is more a security issue - but that is really not needed in most companies. If you now your way around windows (and the phones) you can set DCP priorities easily wihtout ever using a VLAN. Plus 1gbit is a lot - I would say for a smaller install, the overhead in administration even for QOS is most likely not needed. People doing phone calls a lot normally are not the people copying gigabytes to their machine ;) From a practical point. – TomTom Jul 6 '12 at 14:40

two unusual options:

  • softphones - they actually work
  • dect phones with voip-aware base station like solutions from ascom or gigaset.
