Call Drop Issue

santoshmhaske1 · ‎05-03-2010

Hi All,

Randomly we are facing a problem of call drop. We have checked on the gateway and pri level there are no errors.

I have collected the sdi traces from call manager. In the traces i found below error for dropped calls,

05/01/2010 16:27:29.590 CCM|DbMobility: can't find remdest 9971020736 in map|<CLID::StandAloneCluster><NID::10.22.135.22><LVL::Error><MASK::ffffff>

Hi Santosh,

Could you please describe the call flow?

Only one phone 9971020736 ? Incoming or Outgoing?

Always PSTN calls?

Attach complete CCM SDI/SDL traces including timestamps, calling, called number and call flow

For future reference always include complete traces not just extracts

Thanks

Hi,

Actualy we have Call Center setup here. Call comes through Voice Gateway AS5350XM then CVP and ICM.

There are many such calls, I have just provided one example.

All are incoming and PSTN calls.

Attached herewith SDI logs.

Below is the calling numbers and date/time of these calls,

9971020736 - 01/05/2010 16:27

1126479098 - 01/05/2010 20:09:31

9911500081 - 01/05/2010 20:09:51
