Hi Jerry, Have a look at 3pcc-enable option in your sip profile. You may want to set it "proxy", even if it's not that RFC compliant and has some issues with codec negotiation (FS advertise global_codecs to both parties and it may result in having different codecs on each leg => transcoding or call drop if transcoding not possible).
