[Asterisk-Users] Calls to DISA over ISDN PRI don't get CONNECT ACKNOLEDGE
Hi ! I'm having a problem with calls that come over ISDN PRI and go to DISA
app. Problem doesn't happen with calls from SIP phones to DISA or for a
calls over ISDN PRI to SIP phones. Asterisk is 1.2.0
This renders DISA completely unusable when call comes over PRI, since every
call gets hunged up, about 10 seconds after it is answered by Answer or
DISA.
Here is relevant part of extensions.conf:
[default]
exten => 209,1,Macro(superdial, SIP/209,,rtT,,${EXTEN},1)
exten => 299,1,Answer() ;tried without this also, but with same results
exten => 299,2,DISA(no-password)
---------------------------------------
Here is PRI debug of call to DISA:

For a comparation purposes here is PRI DEBUG for a call to SIP phone, over
same ISDN PRI, where the CONNECT message is ACK'ED.

Does anyone have any idea why this is happening, and how to solve this
problem ?
