H.225.0 Annex G v1 - with corrections
H.225.0 Annex G version1 was decided at the May, 1999 SG16 meeting in Santiago. Since that time, some errors have been found and corrections have been included in the Implementers Guide. However, it is not always easy to work with multiple documents (Annex G, Implementers Guide), so I put together a document containing the decided version of Annex G V1 and all the corrections and editorial changes made over the last few months.
Enjoy.

Sir,
I have a small question.I am trying to implement an algorithm for objective testing of voice quality.I need both the test and reference files for the algorithm.My question is if we play a pre -recorded message between 2 H.323 end points(say voxilla/netmeeting).Can we record the talk on the other machine.
The scenrio will be transmitting the voice packets from one endpoint to the other in an emulated environment.I want the other machine to directly store the wav/au file.Is this possible....
I am asking this since i need both the audio files for objective testing.
Are there any endpoints(VOIP) which support this.May i know the answer as soon as possible.

Dear Mr Yamarthy,
Related work is underway in ETSI Project TIPHON and ITU-T SG12. Measurements were made over VoIP connections at the recent SuperOp99 event held jointly between TIPHON and IMTC. Further tests are planned for October 2000.
An analysis was presented at the recent TIPHON meeting showing the correlation between the actual subjective test results and various objective MOS algorithms at present under study in SG12. See Document 17TD135 presented at the Sophia Antipol TIPHON Meeting March 2000. This document is not publicly available to not ETSI members but a good contact for this work would be Harold Klaus, the author who is also the SG12 Q13 Rapporteur.
