Hi, I am experiencing intermitant low volume incoming calls on CME 4.1 with a PRI. Especially and mostly when doing a group pickup of another extension. There is no discernable pattern to the quiet calls, from various local, national and international numbers.
Any help appreciated.

Hi, I suggest you upgrade to 12.4(11)XJ4 that is the most stable release with most bugfixes.
For the phones I suggest 8.2(2)SR4 alsto latest stable.
I have this combo on many customers, but admittedly they don'use group pick-up.

Hi, can you send output of "show controllers E1" or T1. you may be getting slips.

Your right on the slips. here is a partial output. Will this be a provider issue?

No, config issue:
network-clock-participate wic 0
network-clock-select 1 e1 0/0/0
And you will be ok.
Hope this helps, please rate post if it does!

Thanks, I will give it a go and see how it gets on. I will have to leave it for a few days for the company to come back to me.

Sure. Remember, ISR routers need network-clock commands. Older models do not.

The commands have resolved the slip issues on the E1 card. However, I am still experiencing intermittant and seemingly random quiet/silent incomming calls when the call is answered via a group pick-up.
Any Ideas?

Which exact IOS are you using, which phone types and firmware on them ?
02-20-2008 03:17 AM
IOS is spservicesk9-mz.124-15T1 sitting on a 2811 with 64Mb Flash and 256Mb Dynamic Ram.
CUME is 4.1(0)with 2 x 32 PVDM modules.
Phones are 14 x 7941G running SCCP41.8-2-2SR1S all placed in 1 pick-up group.
Direct calls to extensions seem to be fine. The quiet calls are when a group pick-up is done. Also the silence is one way. incoming can't be heard, but out going can be.

Ok, Thanks, I will give it a go and see how things pan out.

Have you resolved these problems? I have exactly the same problems.
03-31-2008 03:17 AM
Have you checked for slips ?
03-31-2008 03:47 AM
Yes I have. And the only problem we have is when we use group pickup. Otherwise the sound is normal.
03-31-2008 05:20 AM
Which exact IOS are you using. If anything lesse than 12.4(XJ4) suggest you upgrade to that.
Thing is I've heard that issue already, but I haven;t a bug to reference.
