asterisk users - Apr 2011 - Problem with E1 (ISDN) + DTMF

Hello, 

I have the scenario: Link E1 with ISDN running with asterisk 1.8.2.3, voicerlib
4.2.3.0, libpri 1.4.11.4 and dgvchannel 1.0.8. Asterisk begins a call, when the
called party answer the call, it asks for the the called party to input some
numbers (via DTMF) but when the numbers are pressed the asterisk shows me the
following error:

[Apr 12 10:47:02] WARNING[3245]: chan_dgv.c:11831 event_handler: *** Channel not
OK, can not receive events when p is null! ****

Somebody knows how can i fix this problem? 

Best Regards. 

Luiz
