By the end of the year, we are going to actualize a ShoreTel telephone framework! What instrument does all of you use/prescribe to screen and pinpoint VoIP system issues? We have assessed Orion Netflow Traffic Analyzer and it worked, yet our issue is that every one of our switches doesn't bolster NetFlow or sflow. We have a blend of HP ProCurve 2848 switches at the center and HP ProCurve 4000m or Dell 3448P switches on the end.
The HP 2848 supports sflow, yet HP 4000m and Dell 3448P switches don't. Any counsel? Only a little harried that we can not discover a device that works with every one of our switches on checking VoIP traffic. I'm attempting to avoid parcel sniffers, for example, Wireshark (like it since it's free!) since it's not as easy to use as Orion's item. We have an IT staff of 2 and neither of us are arrange specialists.
