IS a transcoder required to enable off-net parties to join an ad-hoc conference call? ( the initiator is an on-net party using a 7940 registered to CCM 4.1(3)).
that depends on the codecs involved, if you're using the SW CFB and try to use G729 then you need a XCODER, if you're using a HW CFB with G729 enabled then there is no need for XCODER
SW CFB only handles G711
Thanks a lot Jamie,
this issue is resolved now & I didn't need to configure XCODER once I switched to HW CFB.
Have a nice weekend.
