[asterisk-ss7] Asterisk SS7 as a STP for Number Portability GW

[Virmones Pereira]

Hi,

I would like to use asterisk with SS7 as a STP for Number Portability GW,
the idea of the system is follow:

When the SS7 central(Ericsson AXE) receive the call this should be route to
the Asterisk to trigger the number portability database by SS7/ISUP method
if the asterisk found this destination number in the number portability
database asterisk will insert the Routing Number in the begin of the called
number and then route back this call to the SS7 central.

Ex:

user dial 551132323232 this call go the asterisk and asterisk turn back with
55112551132323232.

I wanna do this operation using asterisk as a STP where the SS7 use only the
signaling channel, the media should go directly to the SSP

somebody knows how to do it?
