Is your PRI dropping calls, or are the unused B channels resetting? What is your resetinterval in the /etc/asterisk/zapata.conf?<br><br><br><br><div class="gmail_quote">On Tue, Mar 24, 2009 at 3:21 PM, Harry Vangberg <span dir="ltr"><<a href="mailto:harry@vangberg.name">harry@vangberg.name</a>></span> wrote:<br>

<br>
I have an ISDN-30 connection and a Digium TE-121 with VPMADT032 echo<br>
cancellation. Every 30-60 minutes I experience PRI dropping.<br>

With PRI debug turned out I get this output:<br>

For each and every channel (see full output at <a href="http://sprunge.us/fUEd" target="_blank">http://sprunge.us/fUEd</a> )<br>
<br>
I have had two technicians from my telco out here and measuring.<br>
Everything is fine with the connection.<br>
<br>
Best regards,<br>
