Well, this is a 1760 running 12.4(15)T9, how do you check for DSP errors?<br><br><div class="gmail_quote">On Fri, Aug 21, 2009 at 10:12 AM, Ted Nugent <span dir="ltr"><<a href="mailto:tednugent73@gmail.com">tednugent73@gmail.com</a>></span> wrote:<br>

We've had very good success with 12.4(15)T8+ as far as MGCP/DSP stability. Cisco has tried pushing me a few time to higher levels of code and I've almost always gone back to this version because of bugs.<div>
<br></div><div>Another note that probably has no bearing on the problem but is a good practice you should lock in your calling numbering type/plan to isdn/national and leave called to unknown/unknown, it can cut down on other issues down the road (provider dependent). HTH</div>
