asked on Setup Network for Voip
Hello. Recently implemented a voip PBX and am having poor performance. Have not implemented any QoS or VLans.
Have Comcast for out ISP with mid tier which is about 50/20.
Have plenty of switches at my disposal. several Procurve 2924s and one 5406zl. All support POE.
I am not an IT professional. Just manage the best I can. Have the ability to set Vlan tags and do most configuration changes if I know what to do. The last time I tried Vlans, I found it cumbersome and problematice with DHCP, DNS and the few locations where the phone shares the same connection for both the phones and the PC.
My Question.
Given that we are a small shop with plenty of hardware. Can anyone provide me some recommendations that do not require an in-depth study of SIP and networking. Just want to phones to work.
My only other option is to segment the entire network physically and put the phones on a different subnet. Do not like the idea of maintaining two DCHP servers. DNS is not a big problem. To manage the PBX have planned to configure two NIC. one to manage it from the regualr network and the other with no gateway for the Voip network.
Any recommendations will be a big help.
Thanks

Each vlan will require its own unique ip subnet.

The explanation does explain a few things. I received this from procurve support.
However, in a much more simple configuration, if you were only going to have phones connected to certain ports, and these would only have phones connected and would not change, then you can simply set the port priority on all those ports to a higher level than the data ports. The priority is a numeric value from 0 to 7, with seven being the highest.
An example of setting up a single port would be as follows, in this example I used port 10:
HPALF2848-1# configure
HPALF2848-1(config)# int 10
HPALF2848-1(eth-10)# qos priority 7
HPALF2848-1(eth-10)#
So at this point port 10 would have a qos priority of 7, which is the highest, and receive the most attention. Any ports that had the same qos priority setting would receive the highest priority, while any other ports would receive normal priority.
The down side is you would have to individually configure each port manually, rather than setting on a vlan.
This sounds simple and I am trying to implement this now.
Aside from the stated downside of configuring port individually, are there any others?
Thanks

No thats the main thing. Static port assignments and the fact that now you need switch ports for all locations 1 for PC and 1 for phone.
From what I am gathering it will not be necessary to have a separate subnet because the vlan is already separating the traffic. Is that correct?
As for the pix we are using 3cx with Yealink phones.
Having the DHCP server provide the vlan setup for the phones sounds great. If that works will same a lot of time as opposed to setting each phone up manually.
