Dear colleagues,

please see in the attached that audio payload formats for G.723.1, called there "G723", has been removed from the latest RTP A/V profile because of the lack on information that interoperable implementations of them exist. Other audio payload formats have also been removed, e.g. H263 (this is not the same as H263-2000), GSM-HR, GSM-EFR, If you know of such implementations, there is still some VERY short time (less than 2 weeks) before the IETF issues the repeat WG last call. Please provide any such information directly to Stephen Casner casner@acm.org.

Best regards, Simao.
