Dear Sirs

Recently, an Amendment was approved to ITU-T Rec.T.38 and a new SDP att-field called "T38VendorInfo" was defined, necessitating its registration in your database.

This request was initially communicated via a Liaison Statement sent to statements@ietf.org on 01/Dec/2004, and in this message I would like to check what is the status of our request, as I was not able to locate a "tracker" tool in the IANA website. I also verified in http://www.iana.org/assignments/sdp-parameters that the said field is not yet available, hence it hopefully is already under processing.

I would appreciate to know when could this registration be ready.

For easier reference, I added below the specific information of the requested registration (between --START and --END).

Your prompt feedback will be deeply appreciated, and we remain at your disposal for any subsequent clarification needed.

Best regards, Simão Campos Counsellor, ITU-T SG 16 Secretariat ("Multimedia").
