Raul, You are on the wrong channel with this question. You question is not Asterisk related, much less lib_ss7 related. You ought to ask to the people behind chan_ss7. It may be okay to discuss a general mobility topic on a BMW list, but you aren?t getting much cheers if you discuss your Mercedes problem on the BMW list despite the fact that both are cars. Regards, Florian PS: If you are a telco and you have local customers being switched to another local customer (=physically connected to the same PBX), you automatically have a dedicated exchange for that and a separate trunk/linkset for non-local calls being sent off to your national or international exchange. Nobody would want what you want anyway so what are you trying to do here? Is this just an academic lab question or why does your network planning require this?
