Choppy calls on CME 4.1

[filiberto.aguirre]

I have a problem with voice quality, the problem began 3 days ago.

if user of CME calls to PSTN , PSTN party listen  CME's user voice choppy

Hi,

I have already checked CME , the only thing that keep my attention was the info
displayed by the following command

#sh memory processor allocating-process totals

kmm-ccme-core# sh memory processor allocating-process totals
addto_mempool_pc_array(): overflow    ----------->>>> ??????

Allocator PC Summary for: Processor
OVERFLOW = TRUE   -------------->>>>>> ??????

    PC          Total   Count  Name
0x60592B74   19640512   20716  *Packet Header*
0x60EA36B4   11855492     149  Virtual Exec

0x604CA234    2158592    1024  Init
0x603F9400    1842400     200  Init

I just paste some part of the info.

This could be the reason of the problem??
Should I check other comands?_

I would look to see the state of the processor and memory on box:

show process cpu history

show process mem history

See if either one is reaching 100%

Is there a local PRI connected for inbound and outbound calls, or they using FXO? See if there are any physical layer problems.

And for an active call do:  show call active voice brief  -- Look at the delay and if you are losing any packets. Here is an example:

FFA : 846 138322120ms.1 +16650 pid:1000 Answer XXXXXXX active
dur 00:00:10 tx:496/9920 rx:495/9900

Hi Jaschulz,

Thanks a lot for your comments and suggestions.

What is strange is that CPU and Memory processes is not high , just some peaks on CPU; I attach the file.

regarding to show call active voice brief  commands I did not see any lost or delay value.

Regards

No problem:

Yes there is nothing to be concered about as far as cpu. But looking at the output of show call active brief, there is alot of noise.

You can adjust the input and output but I suspect a bigger problem with the circuit. I would contact the carrier and have them test,

but unless you are seeing physical later issues on the port they probably will not see any errors either. At the lease you could

replace the cable to the niu.

Hi jaschulz,

Carrier has already checked E1; carrier's staff said that all was right....

I'm going to carry out more tests to check if there is something wrong with cables

Thanks a lot for your time
