[asterisk-ss7] ISUP Signaling probe with modify ability

[Mehdi Shirazi]

Hi
I want to put one signaling probe between two TDM Exchanges(local => transit) and just pass signaling link through this probe (voice channels go directly with 150E1) , this probe should transparently send all signaling messages between two TDM Exchanges except for some A or B numbers list, for this list this probe should REL the call with special Cause Value.
( one application of this scenario is for providing Fixed line prepaid telephony service, don't mix it with prepaid card)
please give me any idea about how to implement it.

Regards
Mahdi
