When Julia Sattout had a Cochlear device implanted in her head five years ago, it didn't just restore her ability to hear again, it saved her career as a lawyer.

But there was one anxiety-inducing problem. Despite using the latest accessories, the simple task of picking up a call on her mobile phone often proved difficult.

"At one point I had a double adaptor, so I had a coil hooked over my right ear and an audio cable I had to plug into my sound processor," said Ms Sattout, 45 of Concord West.

"So when someone rang me, like a client, it was like, plug this in, plug this in, and by the time I was ready, I had missed the call."
