VOIP is very sensitive. What model phones are these and what type of
failover do you have configured for the phones?<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><font color="#888888">
