I have been wondering lately if there is a relationship between the advanced settings in a voip trunk (supports reinvites, etc) and the bpx delivers audio tick box as we found recently by switching this off we improved an inbound audio issue when transferring calls.

It could also have something to do with the audio channels in use on the handsets (internal 7000 range versus the external 9000 range) and the NAT settings on the phones.

These would be the settings to check if call transfer (loss of inbound audio on a transfer or blind transfer of a call) or the choppy sound in the previous posts.
