Newbie to FreePBX/Asterisk and looking for some direction on code changes for a new project I am working on. I would like to modify code to get additional field “REDIRNUM” from T1 D Channel information.
Trap Output from Telcom Provider Traffic during a Forwarded Call to my Asterisk server is below. As you can see the D Channel provides the detail I need (REDIRNUM)
D1 : L3 TX CREF=0004 IE[05]=CALLGNUM (NumType=National NumPlan=ISDN/Telephony[E.164] PresentInd=Allowed ScrnInd=NetworkProvided Digits=636XXXXXXX)
D1 : L3 TX CREF=0004 IE[06]=CALLDNUM (NumType=National NumPlan=ISDN/Telephony[E.164] Digits=404XXXXXXX)
D1 : L3 TX CREF=0004 IE[07]=REDIRNUM (NumType=National NumPlan=ISDN/Telephony[E.164] PresentInd=Allowed ScrnInd=None Reason=Uncond Digits=636XXXXXXX)
Currently the CALLGNUM is passed on to Asterisk as the CALLERID. See details from full log:

I am using Sangoma A101E with the following:
FreePBX 2.5.2.1
asterisk-1.6.1.9
libpri-1.4.10.2
dahdi-linux-2.2.0.2
dahdi-tools-2.2.0
wanpipe-3.4.8
Linux 2.6.18-164.6.1.el5
I looked at /asterisk-1.6.1.9/channels/chan_dahdi.c but am not clear on how to access and pass this variable. Any pointers on getting started would be greatly appreciated.
THANKS!
