One way audio is usually caused by the router.
Please make sure SIP ALG function of the router is disabled and the right RTP ports are forwarded/opened to the IP phone.

Hope this helps.

Thank you so much. This did the trick.

The bit that confuses me, is that I hadn't done this when I first got the phone and it worked.

Thank you again for your help
