[cisco-voip] Call Drop

[Sovannary]

Yes, I guess that's the only way as I'm not so technical.

 

Thanks for your help.

If the problem is happening that often (not knowing you total call volume
for a day) - I would think it would be fairly easy to span the port on one
of your "frequent droppers" and get a packet capture as well as digging into
some "detailed" CallManager traces.  These combined should give you an idea
on which end is initiating the disconnect.  If you are unfamiliar with
either of these - the suggestion to contact TAC is your best bet - they'll
get to the bottom of it with you.

Hello,

 

The calls are from PSTN to internal. We are operating a Call Center. We only
got problem for the incoming calls. 

 

There is no data log for CDR. 

 

What do you mean PRI/E1 look? Down? 

I think it's not coz we still received calls but just the number of dropped
call compare to last time are big different number (now the number of
dropped call are up to about 300 calls per day).

 

The calls drop when connected. 

 

Thanks for your help.

Can you give us more to go on that - the calls were being dropped?

Were they internal to internal? PSTN to internal? Internal to PSTN?

What did the CDR's show? 

What do your PRI's / E!'s look like? 

Are the calls being dropped coming / going out a certain GW?

Did the calls drop when transferred, when connected, in the middle of the
call, etc?

Hi all,

 

Recently we're experiencing lots of call drop. We are using CallManager 4.2.


 

Does anyone know what could be the reason for this issue? 

 

Thanks,
