I have a 3745 with a lot of slip secs and error secs on the controller. I am not versed in voice yet but I can tell call quality is not great. Some users report that callers cannot hear them.
3745#sh controller T1
T1 0/1 is up.
Applique type is Channelized T1

Also configured on the router:
no network-clock-participate slot 2
network-clock-participate slot 4
network-clock-participate wic 2
network-clock-select 1 T1 4/0
Can someone point me in the right direction to troubleshoot?

Add wic 0 to network-clock-particiapte, i.e. network-clock-participate wic 0.
Can you also provide "sh network-clocks"?

Here is the result of the sh network-clocks command:
3745#sh network-clocks
Network Clock Configuration
---------------------------
Priority Clock Source Clock State Clock Type
1 T1 4/0 GOOD T1
10 Backplane GOOD PLL
Current Primary Clock Source
---------------------------
Priority Clock Source Clock State Clock Type
1 T1 4/0 GOOD T1
Can you explain what network-clock-participate wic 0 does?

Your controller output shows you have a T1 circuit in port 0/1 assuming this is your voice circuit you are having issues with, you want to make sure it participates in clocking as all voice circuits and DSPs need to. Clock slips/errors are caused by not having proper clocking participation as evident in your environment.

Will I need to schedule maintenance to put in these commands?

Depends on your change management process, but applying this command does not cause any outage.

Thanks Chris. I'll try this out and post back the results tomorrow.

I tried to insert the command:
network-clock-participate wic 0
The response from the router was:
WIC slot is empty or does not support clock participate
Which commands can I use to display all the WICs?
