Avaya B179 Conference Phone Voice quality issue

[Jimbo2015]

I have set up the conference phone on an IPO V2 on release 9.1 going out over SIP lines.

The Voice quality on all 110 of the Avaya 9611G's and 2 x Dolby Conference phones is fine but the two Avaya B179 conference phones are occasionally having issues. Any idea what might be causing this?

All calls are going out over G711a so should I allow another codec for these instead?

TIA,

Also please could you let me know the latest level of firmware as I have seen references of 2.4 but can only find 2.3 firmware to download on the Avaya portal

They are still having issues with voice quality on conference calls. We have selected G711a on both the SIP providers portal and under line on the IP Office but both the H323 extension setings and under System VoIP settings all codecs are selected.

Please could you let me know if I should also amend these settings to G711a also and if you think this will improve the voice quality?

Many Thanks,
