Ed, I wouldn't think my internal calls need to go through the 2801. CCM and Unity hang off a 3560G (along with a 3560POE and the 2801). So my assumption has always been the call gets 'built' through the CCM, the 'route' is then set, and then CCM can drop out of the picture pretty much. But I will need to confirm that.<br>
<br>Thanks. I'm going to go dig through the Cisco site now for that document. My 2801 is running 12.3(11)T9.<br><br>Todd<br><br><div class="gmail_quote">On Sat, Jul 12, 2008 at 1:11 PM, Countryman, Edward <<a href="mailto:Edward.Countryman@provena.org">Edward.Countryman@provena.org</a>> wrote:<br>

<p><font face="Times New Roman" size="3"><span style="font-size: 12pt;">Environment:<br>
<br>
CCM 4.1, Unity version 4 also.<br>
3560s, 2801s. 6 buildings all linked by fiber. Each building has a
2801 and 3560.<br>
Total phone count: 60, mostly 7940s, some 7912s, a few 7960s.<br>
<br>
All fiber runs back to main location where it joins the network through GBICs
on 3560s.<br>
At the main location we have a PRI that goes into a 2801.<br>
<br>
Problem: 3 times in the last year, we will get a situation that goes like
this:<br>
Pressing 9 to dial out, and dialing your number: Phone shows call is
completed, starts counting the seconds, but you hear nothing.<br>
If we call another extension internally, they will hear us but we cannot hear
them.<br>
If someone calls in from outside and gets the auto attendant, no input is
accepted, the attendant just keeps going. (i.e. Press 2 for this, she
just keeps going, you can press as many buttons as you like, no change).<br>
<br>
The solution seems to be to reboot the main 2801 with the PRI. I am not
sure why this would cure internal extension-to-extension calls, but it
does. My facility runs 24 hours a day, so a reboot is never a good thing.<br>
<br>
Where should I start looking? Broadcast storms? Is this a sort of
known bug that Cisco might have fixed somewhere? Anything in Unity or CCM
I should look at? Counters on ports?<br>
<br>
Would appreciate any direction at all!<br>
<br>
Todd</span></font></p>
