Voip cabling 2

[Rickg47]

If you use your company data network and voip phones should all the work stations go to a patch panel.If you have existing network stations that have had a switch added to
service other workstations, should they be replaced with
individual runs back to a patch panel, or will voip phones work through switches?Don't really know much about voip, but
concerned about existing cabling if the change were to be made.

A VoIP phones is essentially a computer which happens to be run an application called "voice" so think of cabling it the same way as you would an etherner-connected PC. You still have ethernet cable speed/distance limitations between the phone and data switch depending upon the type of cable (cat 3/5/5e/6) you are using. You still need to have the IP address of the PBX reachable from the phone (or vice-versa) but this can be through a router. Most VoIP phones do have an integrated switch which allows you to use the same single lan drop for the phone and a co-located PC.

So you could have a network run A going to a office and terminate on a say for example a 4 port ethernet switch and
co-locate a pc and voip phone on each port

most voip phones have a port to plug in a PC so you could patch your phone into the ethernet drop and patch pc to the phone and not need a hub or switch at the station

What am asking is in regards to rewiring or not.A number of offices have multiple workstations.There is one cat5e to
that office. The single network run goes into an ethernet switch and the multiple workstations in that office are
coming off the ports of thst switch.Would this work with
co-located phones and pc's?

It will work but is not optimum. You are backhauling all of the data to/from those multiple workstations (and phone) over a single link. If you do not have any mechanism to provide QoS to the phone, you are likely to run into voice quality issues.
