[asterisk-dev] ISDN Cause Code 100, Bosch Integral Management Connection

[Wolfgang Pichler]

Hi all,

we have the following setup

PSTN 3 PRI Lines   <--->  Asterisk (1.4.22)   <--->  Siemens  HiCom   
<--->   Bosch Integral

The Asterisk Machine does play the man in the middle - and adds some 
extra functionality to the system (SIP users...) - the normal calls are 
getting 1:1 through the system (incoming calls from PSTN are handled by 
a simple Dial(ZAP/g1/${EXTEN}) (g1 = Siemens side) - so no special 
handling here...

Everything is working as it should - beside of one little thing. The 
Bosch Integral PBX does have a special extension (99) which is used to 
remote manage the machine - this managment connection is working fine 
without asterisk, as soon as asterisk is connected in the middle the 
management connection wont work any more - getting back isdn cause code 
100. I have already tried dial options d und c (make it digital - clear 
channel) - no success.

Here is the isdn debug

The ZAP Lines comming from PSTN are configured as follows
group=0
context=from-pstn
switchtype = euroisdn
signalling = pri_cpe
context=fromPSTN
internationalprefix = 00
nationalprefix = 0
localprefix = 0732
overlapdial=yes
pridialplan=unknown


The ZAP Lines going to the Siemens System are configured as follows
group=1
switchtype = euroisdn
signalling = pri_net
context=fromPBX
internationalprefix = 00
nationalprefix = 0
localprefix = 0732
overlapdial=yes
immediate=no


The zaptel.conf does contain
span=1,1,0,ccs,hdb3,crc4
# termtype: te
bchan=1-15,17-31
dchan=16

for each span

The system is located in Austria...

Can anyone here imagine what could go wrong ?

Best regards,
Wolfgang
