color:#1F497D'>Have been looking at it a bit more, and it looks like the
internal calls are all PCMU, so when the call is put on hold, and a new call is
made before transfer, the new call will be PCMU. If the call is not transferred
(As is the case with the sample I sent to Brian), I would expect it to go back
to PCMA, and as far as I can tell it does, but the recording quality is still
good, so don’t think it is the codec in itself, but maybe something don’t get
initialized correctly until PCMU is used!?<o:p></o:p></span></p>
