Can you be a bit more specific about your problem?Did you mean they can't use 6 lines in the same time??

Thanks for the speedy reply.

The user is stating they cannot use all 6 lines at the same time but can only obtain 4 calls at any one time, however this happens intermitantly. During my investigation I have seen 5 calls active at any one time, my only concern is the error message previously mentioned which is contained within the log, I would like to rule this out as to whether this could be causing the intermitant problem.

The version of software we are using is:

c3640-is-mz.122-1a.bi

Any suggestions will be greatly appreciated. Thanks

Hi,

If you look in the Bug Tool there are about 30 bugs for this error message

The one that might interest you is ...

CSCdr98683

occasionally getting VTSP-4-FSM_BAD_EVENT and call getting dropped

This one is still open

But in general my impression is the error is generated after the call completion and it shouldn't cause you this problem.

I'm just wondering what is happening when you are trying to place the 6th call ?
