Description:When you dial into DISA app over ISDN/PRI Zap channel, DISA doesn't get
CONNECT ACKNOLEDGE and hangs up about 6 seconds after entering DISA app. This DOESN'T happen on X100P, TDM400 or SIP calls, nor it happens when I call SIP phone over a same ISDN/PRI.


relevant part of extensions.conf for two pri debug logs below:


exten => 209,1,Dial(SIP/209,,tT)

exten => 299,1,Answer()     ;tried without this also, but with same results
exten => 299,2,DISA(no-password)

This is not an Asterisk bug; if the other switch does not send CONNECT ACKNOWLEDGE, we must drop the call when the appropriate timer expires. There is no other possible behavior.
