[reSIProcate] terminate a subscription before onNewSubscription(ClientSubscriptionhandle) is called

[Mayur]

Hi,
   I would like to know how I can terminate a subscription for which I have
not received the sync Notify, i.e. before onNewSubscription/onUpdateActive
is called. In this case I do not have the ClientSubscriptionHandle through
which I can use end() to terminate the subscription. 
Using AppDialogSet end() does always seem to help because if any provisional
response has been received then my DialogSet state is ReceivedProvisional
and then assert(0) is called.

Regards,
Mayur
