My quesitonn is , with the osmocom-3G and the box nanocell3G for example; it is possible to send ss7 message like sri-for-sm, ...!?

FYI: SRI-for-SM is not a SS7 Message, but a MAP message. MAP runs several layers on top of SS7. However, SS7 is used for much more than just MAP.

In the osmocom stack, we currently do not support TCAP/MAP.

There have been several attempts in the past, like

* C language libosmo-tcap + libosmo-map (abandoned ~ 2012) * Erlang language "signerl" used in some real-world scenarios but development discontinued in 2013): http://git.osmocom.org/erlang/signerl/

* A Smalltalk implementation that Holger did (I don't have a source code link around)

There has never been any contribution (in terms of code or funding) to have a proper MAP implementation in the Osmocom stack. Today, the best approach to do this is to implement a proxy between the GSUP protocol and TCAP/MAP on the other side.
