I just brought up a site that should use only G729 between other sites and internally. Reviewing CDR data I see a occasional call using G711. Most of these calls go to Unity but I can see no reason why this would be. There are also calls to Unity that use the correct G729 codec. I have verified that the regions are all set up correctly and that all of these phones are in the correct Device Pool that contains the G729 Region. I see no errors indicating a lack of transcoder resources. Any advice on how troubleshoot would be appreciated.
