Gordon, thanks for such a detailed and full of information email. It helped me and must have helped hundreds of others on this mailing list.<br><br>In my scenario, for this client whom I am working for, their main issue has always been echo. They have about 50 extensions, with 20 in the office, busy office, calls all the time, up to 5 at any given time, 10 remote extensions and other virtual extensions just for voicemail purposes. 5 IVRs and 4 queues, one VoIP line and main trunk a T1 PRI. PRI is used for all incoming and outgoing calls except for long distance calls where VoIP line is used.
<br><br>I am thinking of going with HWEC and also using a good QoS switch. Right now there is only one switch (don't remember the name) and it is handling all the VoIP and data traffic. Sometimes voice breaks, and it must be because of interference from data traffic. But this is not a very serious problem and one switch with QoS should be able to handle it. Am I right here? Even if someone starts using P2P software.
<br><br>Current router is a linksys <span class="text-blue-large">WRT54GL - Wireless-G Broadband Router. Is it good enough if I get a good switch? Can you suggest which switch I should get. I was looking on the Internet and found switches like
</span>Adtran NetVanta which are very expensive. What do they do which makes them so expensive? And in my case, is that the type of switch which I need or is there something cheaper out there too. I am ok without PoE.
