VOIP is very sensitive. What model phones are these and what type of
failover do you have configured for the phones?<br>
<a class="moz-txt-link-freetext" href="http://puck.nether.net/pipermail/cisco-voip/2009-May/001155.html">http://puck.nether.net/pipermail/cisco-voip/2009-May/001155.html</a><br>
<br>
The failover type determines TCP stack behavior on the phones. The
underlying cause is dropped or delayed packets in your network. Other
applications are just more forgiving.<br>
<br>
You can try "slow failover" to be more lenient on signaling. However,
if you are running RTP over those links the RTP will still be
negatively impacted.<br>
