I have a client with 2 sites which are connected by a layer 2 2/2 Mb Bridged DSL connection with HP Procurve Switches at each end we are placing VOIP calls over their network between the sites
I have set up 2 VLans one for the voice network which is tagged with a priority of 6 and 1 for data untagged with a priority of 2.
If I use Wireshark at either end I can see that the VLan tagging is working and being passed from site to site.
The problem that I am having is if we try to do any type of file transfer between the sites call quality suffers QOS via the VLan tagging doesn't seem to be working. I can make 6 or 7 calls and access the internet between sites without a problem but as soon as we try to traaansfer any type of file accross the WAN Link the call quality starts playing up.
I have been told that because the ports on the Procurve swhich are connecting the sites are 100Mb they will need to be restricted to 2Mb because the ISP's equipment in bridged mode cant do any of the prioritizng.
We are using G723.1 (MP-MLQ) as the voice codec
