<p>I have 8 aastra phones that are loosing registration. On the phone gui it says 408 as the registation error after a minute or say they register. In the cli it eill say the phone is now unreachable then it will show it registering then available. At first they did it every hour all the phones. After messing with the experation it does it every 15 nin.</p>
<p>Any ideas on how to troubleshoot this? I tried a debug on the phone in the cli but I ended up with over 100 pages of text. Via sip show debug peer 2000 or something like that.</p>
<p>Respectfully<br>
