Hi, guys, I set up an asterisk box with a TE410P and connect it to a local carrier using Dicea's chan_ss7. In my situation, the carrier forwards calls to several different numbers to a static one to simplify the routing procedures. I was told that the callee's number (B-number) can be fetched from IAM message. The chan_ss7 works just fine for voice connections. However, I have no idea how to obtain the Original Called Number in asterisk's extensions.conf. Neither ${CALLERID(dnid)} nor ${CALLERID(rdnis)} works for me. Any clue?
