[Freeswitch-dev] PRI/OZ Question: In-band Busy signal

[Michael Collins]

FYI,

 

I think possibly I found a case where the OZ/PRI needs to change from
PROGRESS to PROGRESS_MEDIA:

http://pastebin.freeswitch.org/4628

 

In this case I'm getting two PROGRESS messages in a row.  The raw Q931
messages are:

 [08 02 80 0c 03 1e 02 81 88]

 [08 02 80 0c 03 08 02 81 91 1e 02 81 88]

 

The second progress msg includes: 08 02 81 91 which means:

08 = Cause IE

02 = two octets/bytes

81 = 1000 0001 = pvt network serving local user

91 = 1001 0001 = Cause number 17 = user busy

 

I'm 99.9% sure that as soon as we get this PROGRESS info that we can act
on it.  MikeJ, is it possible that the result of the originate command
can be something like -ERR BUSY instead of -ERR NORMAL_CLEARING?

P.S. - I think this case also shows that we don't need the warning
message:

2008-06-16 19:58:22 [WARNING] zap_isdn.c:411 zap_isdn_931_34() Why
bother changing state on 1:1 from PROGRESS to PROGRESS
