My sip client is not notified when call is cancelled
 

Hi.
I use Nimbuzz > Voxalot > My sip account from Betamax clone.
If I use Nimbuzz > Betamax, everything goes fine.
If I use Nimbuzz > Voxalot > Betamax, if the person I call "cancels the call", my Nimbuzz keeps calling (I hear just like if the person is not answering) - at this point and depending on the receivers terminal, either his telephone keeps ringing (kind of ignoring the cancel order) or cancels the call but starts ringing again after a few seconds.
Another issue happens when the receiver terminates the call - my Nimbuzz does not receive the "Ended call" notification.

Can someone help me with this?

Am I alone in this forum?
