I want to use LibSS7 2.0 with freeswitch.

There is a DAHDI internal loopback feature that can connect a minimal Asterisk instance  with Freeswitch instance in same machine over internal DAHDI loopback

 E1 PRI.

E1(SS7) -->DAHDI-->Asterisk-->PRI--> internal DAHDI loopback-->Freeswitch

-Do you think this approach is more stable than converting SS7 to sip with Asterisk

because Asterisk have minimal modules and just uses DAHDI internal native bridging ?

-freeswitch  debian binaries already included freetdm module for libpri ?
