<div>I'm not sure I've got the opportunity to do that at the moment, but I do appreciate the point of view of a fellow product user. Were you able to eliminate noticeable lag, or just reduce it to reasonable levels?</div>

<div>I'll try to do something similar when I update to the newest trunk as Anthony suggested. My copy is only a week old, but I'll try whatever has a chance of working, and I know you guys have been working on conferencing (the Moderator function couldn't have been timed better for me!).<br>

<p><span style="FONT-SIZE: 11pt; COLOR: #1f497d">Once I knew the delay was solved I raised the sample rate to 8000. I tested it to make sure it would work properly.</span></p>

</div>
<div class="im">
<p> </p>
<p>I'm creating a conferencing product for use in a system with theoretically several hundred concurrent calls. I'm using FreeSwitch to create this product, but am not only new to FreeSwitch, but also the entire telecom industry as well as Open Source projects in general (I'm a recovering BIOS guy).<br>
<br>I've got a bare-bones conference up and running on the server, including a handshake and a couple of features, and am using the default packages from the current trunk, but I've noticed that voice lag is a pretty big issue. Common lag times are several hundred milliseconds, and I've heard as long as a second. It seems to be at least marginally specific to individual phones -- certain phones have longer lag than others even on the same call.<br>
<br>My question is really about what my options are. Is this just a part of SIP? Of conferencing? Of FreeSwitch? Are there things I can prune or slim down that will help? Is this a common issue? If it's common, is it expected by the marketplace? </p>
