SS7 in asterisk 1.4 ?

[plugworld@xxxxxxxxxx (Ruddy Gbaguidi)]

Hi All
I have read a lot to be able to setup our upcoming SS7 link from our Telco.
I finally choose to go with libss7 since it's much like libpri I think 
and it should work ok.

When I compile libss7 and asterisk-1.4, I don't see ss7 related cli 
commands like
ss7 show linkset x
ss7 debug linkset

And there is no mention of ss7 on asterisk-1.4.22 source code.

Does 1.4 support ss7 or I really needs to install asterisk 1.6 ??

Thanks.
