Summary:                    answer() accepted without receiving CONNECT
ACKNOWLEDGE from the ISDN network
Description: 
Hello,

Our system is composed by:
   linux - 2.6.26
   Asterisk - 1.6.2.0-rc2
   dahdi-linux - 2.2.0.2
   libpri - 1.4.10.2
   HW Digium TE420

We verified that some calls are considered correctly accepted and
registered in the CDR as ANSWERED, even when there is not a CONNECT
ACKNOWLEDGE received from the E1 line, as you can see from the signalling
traces. Included are 3 traces.

We have found several of these situations.

This appears to be related to periods of intense calls receiving.

Also it appears that there are no response to STATUS messages from the
network.

Thanks in advance for any help to solve this issue.

Regards,
Leonel
