Has anyone got a clue what the cause of the noise could be on the attached RTP au file?

This stream is from the caller (outbound) end of a NS700. Noise is there on DT and NT handsets.

Callee side has a crystal clear line and cannot hear any noise

If you lower the handset volume then the noise lowers too however it gets much harder to hear the call.

If you turn up the volume to listen to get the true nature of the noise. Seems that sometimes on speech you get a subtle echo

Any ideas?
