I've already done some extensive debugging in the code..
And although I'm not to familiar with this part of the code I think I've
found the possible source of this problem:

It looks like the 'dialed_interfaces' are copied during the first blind
transfer from channel SIP/401 to channel SIP/403 via the datastore
inheritance.
This causes the channel of peer 403 to contain an entry for peer SIP/401
being dialed (from the first call). This entry still exists after the
second transfer since the channel belonging to SIP/403 is not affected.

IMHO we should prevent the 'dialed_interfaces' to be copied in case of
blind transfer by the calling party.

Offcourse I might be totally off here ;-)
As I said; I'm not too familiar with this part of the code.
So I could use some help...
