We are using dm3 DMW1200 E1 cards with external SIU520 for signaling. In order 
to make everything work, driver.cpp need's to be changed to open ss7 device 
(":L_SS7:N_dtiB%dT%d:P_%s:V_%s").  trunk.cpp was also changed, for parsing 
additional messages in IAMa and applying eACM to achieve charge free calls. If 
interested, I can post that changes.

REL is release and RLC is release complete ISUP message. I'm interested how you 
solve short call properly. Can you send me changes you've made?

This is interresting,
 
You are using globalcall with SS7, can you let us know what drivers version and 
board you are using.
I do not know bout REL or RLC 
 
I know the fix I use are working with Globalcall/Isdn.
1.000.000 calls and 99% asr with all the Ports/DS0 still running.
Performance is good even if I am still running redhat 7.3 (I should make 
dialogic work on redhat9 at least since the threading as been improved).
 
If this is a real problem for you I could verify the CVS version I am still 
using a modified bayonne-1.2.13-OWI.tar.gz (Because there was to much quick 
customization requirement for us, I did not follow the Bayonne structure enough 
whe implementing change.)
 
However I could verify the CVS version to see if the 2 problems I have 
indentified are fixed.
1 - Short calls and abandon calls handling.
2 - Multiple CRN's support 
 
I would recommend activating globalcall event logging it is always good to know 
"Bayonne state" and "Globalcall state" when a problem take place.
Globalcall can behave abnormaly when there is shortcall and abandon calls but 
with proper handling no problem.
What I did was to use syslog-ng over the network to keep full logging while 
running lots of traffic.

        Cool...I have some "filthy" services running on top of 20050116 release 
(odbc...) and with couple of 100k calls per day this is not so rare event. 
Beside that it is rock stable.

        I suspect this issue is related to what I am thinking of with handling 
of call state in gc, especially for short calls, vs how the Bayonne state 
machine ends up processing them and what Bayonne believes the call state is.  I 
may jump all the way back to 1.2.11, and roll forward some changes selectivily 
as well as some of my own ideas about having a call cleared flag for this.

        >Hmm...one thing I think we should do is add a "cleared" flag to the 
Dialogic trunk structure. This would be used to indicate that the current call 
had been "cleared" (channel reset after a failure, for example), but that the 
driver (bayonne state) is not yet "idle". This could happen if we reset a 
channel and issue a hangup signal event to the script engine to handle call 
exiting scripts, for example.
        >
        >Hence, in the example you give, instead of issuing TRUNK_CALL_FAILURE 
in response to the TASKFAIL, I think we should instead raise the cleared flag, 
and post a TRUNK_STOP_DISCONNECT. The hangup state handler, when it is later 
called, would check the cleared flag, and skip hangup if the channel is already 
"cleared". The idle state would reset the cleared flag on entry. If a new call 
is presented in postEvent while the current call is still clearing, then it 
should send back a call reject. This I think is also related to the 
simultaneous CRN issue.
