I have one freesbc installation for testing and have one problem. I got 2 intefaces- 1. is for SIP trunk by provider and 2. there is connected sip trunk to genesys. To genesys i have connected Microsip and- From Microsip i make external call to mobile number- everything is okay mobile ringing. But from microsip doesnt go dialing tone (there is silence). When i hangup mobile everything is OK i hear everything. I checked call logs and i found translation - my FreeSBC translate SIP info (RINGING) from external siptrunk to internal sip trunk but there is PROGRESS. I dont know how to disable it- i need info about ringing to internal trunk too. Can sameone help me? 
Thanks a lot
