Call disconnect while trying to transfer

[dimpoo]

Hi!

I am facing a peculiar problem.

The call center agents are complaining of customer calls getting disconnected when they are trying to transfer calls.
I had traced the alarms and errors but there were none.
Then later on system started showing TDM Bus errors on all PN's.
When i traced a station which complained of disconnect problem very frequently, this is what i got.

Is there something I am missing? Is this a hardware problem ?

Please HELP.

Thanks
