[Freeswitch-users] SIP bridge

Hello I have a internal equipment and I want to use a gateway FreeSWITCH servers against some providers. Let me know if it is possible to transfer SIP messages (bridge), such as early media, etc.. I would like these messages to stay at the gateway and not reach the supplier, Is possible?. I've been looking for information but have not found anything about it :-(. Thank you very much. Best regards Anto
