<div>Yep, was think about something along those lines in conjunction with what I mentioned earlier wrt SIP traces etc.</div><div><br></div><div>Were they using their own SIP endpoints to gather that data or was there heavy lifting (adding an appliance, server etc.) in the network required?</div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">One thing we've done for a couple customers in the past is write a<br>
script that initiates a call (via AMI Originate command) out of a<br>
termination provider, which loops back into an origination provider and<br>
is received by the same Asterisk instance. Once the call is<br>
established, DTMF digits are passed and verified received in both<br>
directions.<br>
<br>
If this fails to take place or if the incorrect or incomplete digit<br>
sequence is received, an SNMP trap was thrown via System().<br>
