In the 2 ringing, I put the phone down (dahdi/3). No running the hangup of
channel 3 (dahdi/3). Locking (dahdi/3) up the call by the channel 2
(Dahdi-2).

occurs in versions of Asterisk:

asterisk-1.4.30;
asterisk-1.4.31-rc2;
asterisk-1.6.2.6;
asterisk-1.6.2.7-rc3;

If needed, I can send more information.
