Avaya IP Softphone and VLANs / dot1q tagging

Hi all

We are in the process of planning the installation of a new IP500 v6 into our network. For IP handsets the setup works (at least in testing) with a separate VLAN setup for Voice and various other VLANs setup for data.

One thing that worries me a little bit is the group of IP softphones that will be used by our call center staff. They will not have IP handsets.

How does the softphone work when it comes to tagging traffic? I know for a fact that the NICs in my PCs can't deal with 802.1q tagging, but I was wondering if there is a way for the softphone client to do that instead?

If this isn't possible, how would I deal with prioritizing traffic in that subnet?

The original idea was to keep the voice network clean - with no routing between this VLAN and the data VLANs.

We are considering just creating a new vlan for all of the call center and prioritizing the whole vlan, but that's not ideal as the voice traffic could still be affected badly when the network gets a bit busy.
I would suggest not even using softphones  for a call center environment we have them (call center) and its nothing but trouble I wish we could go back but unfortunately no.  Your are going to have a lot of complaints, people hear echo, calls not as clear this or that and then the headset are a whole other issue.

you could replace the NICs in the call center PCs with VLAN aware NICs. Then run PC on data vlan and soft phone on voice vlan.  However, I tend to agree wtih voipman, softphones are so problematic.  I hate them.  One way audio, headset issues, echo.  Pain in the butt

Thanks guys. We'll take that onboard.
Just FYI, the IP500 VOIP Switch has two lan interfaces, that can be configured independently. So you can just stick one on the data network and point your softphones at it.

Hi MemreLeek (nice handle)

That's what we're doing at the moment. The softphones are just in our data LAN - and surprisingly, we have little complaints.
