Well two "techs" from our Avaya SMB Expert Business partner showed up today to try to fix the lousy voice quality on our IP Office system. (The voice quality on IP Office, using IP office phones internally is roughly cell phone quality.) They attached a Fluke network monitor trying to identify the issues. At my suggestion, they did reground the system.
They haven't found anything yet, but are running around resetting phones to make sure that all the phones are using G711 coding. You would have thought that they would have set up the system correctly at the beginning.
Stay tuned for more updates on the voice quality.
