Hi Don and others.
Finally, we've set up our Asterisk with ISDN service. At the edge of our
network, we can see all three numbers we are interested in as follows.
D1 : L3 TX CREF=0004 IE[05]=CALLGNUM (NumType=National
NumPlan=ISDN/Telephony[E.164] PresentInd=Allowed ScrnInd=NetworkProvided
Digits=3333333333)
D1 : L3 TX CREF=0004 IE[06]=CALLDNUM (NumType=National
NumPlan=ISDN/Telephony[E.164] Digits=2222222222)
D1 : L3 TX CREF=0004 IE[07]=REDIRNUM (NumType=National
NumPlan=ISDN/Telephony[E.164] PresentInd=Allowed ScrnInd=None Reason=Uncond
Digits=111111111)
In Asterisk configuration file (version 1.6.1.9), I can refer to caller id
number via ${CALLERID(num)} variable. My question is how I can refer to the
redirecting number (REDIRNUM)? Which variable should I use?
Don mentioned about Redirecting Number Information Element (IE). Is there a
way to access those IE values within asterisk configuration files? Note that
I also tried DumpChan(). However, I don't see this REDIRNUM (1111111111)
printed out anywhere. Does anyone know if Asterisk actually passed on the
number to an application or configuration? If not, which source code files I
should start looking at to add the feature? I've looked at chan_dahdi.c but
it's a bit overwhelming. Any guidance would be really appreciated.
Thank you for your help.
