[Freeswitch-users] Can FreeSWITCH act as a SIP Proxy with transcoding?

Hi all, i would like to know if FreeSWITCH could be used as a simple SIP Proxy in order to: - receive SIP/TLS connections - receive SRTP secured connection - forward it in "unsecured" way to a backend PBX (plain RTP, plain SIP/UDP) - if required configured do simply transcoding before forwarding calls to backend PBX So to run it as a "SIP Security Proxy" in front of an existing SIP PBX doing also transcoding if required (in case backend SIP PBX does not support SIP UA codecs) . Is this setup feasible with a FreeSWITCH? Does anyone know if cudatel (https://www.cudatel.com/) support such kind of configuration scenario? Fabio
