asterisk users - Apr 2005 - Agents CallBackLogin and HangUp to calling party on pick-up

Hello,

we have setup a queue with a couple of agents, all of which are joining 
in via CallbackLogin. 1 out of 10 calls coming into the queue will get 
hung-up upon as soon as the agent picks up the phone.

We are running 1.0.6 bristuff RC7k (single HFC-card). SIP phones, ATAs 
and outside mobile phones.

Anyone else experience this kind of behaviour?

Anything I can do to pinpoint this problem?

Thanks for any pointers.
