Since upgrading from v16 (which seemed to go well) users complaining of one way audio on inbound calls. Internal and outbound are fine. Finally figured out that switching off the IVR and making all phones ring in a ring group got round the problem. However user then report that 1 way audio happens when transferring calls, which is presumably why the IVR was broken. Any thoughts?
