Do these switches support VoIP ?

We use the following CISCO CATALYST switches in our network infrastructure:

2950, 3524, 3548 and 4006?

Now we consider to introduce VoIP?

Do these switches support VoIP or must they be replaced by others?

Thanks a lot

Re: Do these switches support VoIP ?

We use 2924s, 3524s, 3550s, and 3750s, so I suspect the first 3 you list will support VoIP just fine. Don't know anything about the 4006. I think the only real difference between VoIP and any other application is the configuration of the "voice VLAN" and Class of Service assignment when another device is connected to the switchport in the IP phone. Different switches seem to have different ways of configuring this, but the functionality is supported on all the switches I mentioned. Power over Ethernet (PoE) is another issue, but there are other ways to power your IP phones if the switches don't support PoE.

They will all work with VoIP. The only issue you might run into is limited QoS functionallity on the discontinued 2950, 3524 and 3548s.
