Is there any firewall between the ATA and the CallManager, or between the ATA and the other IP endpoint of the call?<br><br>You might need to SPAN the switch port the ATA is plugged into and get a packet capture to see if the RTP stream really is healthy the entire length of the call.<br>

<p>Good afternoon,</p>
<p> </p>
<p>I have a customer who has reported problems with ATA186's
dropping out for calls longer than 20 or 30 minutes. Has anyone seen this
before and can recommend a course of action?</p>
<p> </p>
<p>I am assuming that this problem is not related to FAX issues
(pass-through or relay) because the reported problem is for long calls over 20
mins. (I can't recall too many FAX calls lasting longer than a minute or
so) I'm guessing this setup is being used for an analog conference phone
maybe?!?</p>
<p> </p>
<p>Thanks guys.</p>
<p> </p>
<p>Cheers</p>
<p>Dana</p>
