string ep_codec_string contains the "endpoint" codec string on the A leg. This codec list includes only the codecs that both the A leg and FreeSWITCH agree upon. This variable is set only when inbound-late-negotiation is enabled on the SIP profile.

(info) When there is more than one codec in the list, the order of preference is chosen by FreeSWITCH, not by the A leg.
