Optus landline call forwarding to Terva

Use this if your practice number is an Optus home phone or Optus office phone. Which codes work depends on the kind of office line, so check your bill.

Your phones ring first, so the front desk gets the first chance to answer. Terva answers when nobody picks up.

Your Terva number

Enter it once and every code on this page uses it. Copy works once it’s filled in.

Type the codes into the dial pad yourself. iPhone blocks links that turn on call forwarding, so there’s nothing to tap.

Turn off voicemail first

Voicemail or a recorded message that answers first stops the call reaching Terva.

If voicemail answers your line, ask Optus to turn it off before you set up forwarding, or it answers before Terva.

Choose when Terva answers

We recommend When no one answers, left on all the time. The rest are optional.

Aim for a 15-second ring time. 10 to 20 seconds is fine. If calls enter a queue, set the caller’s total wait to about 15 to 30 seconds.

Turn on Call Divert online first. Optus says this can take up to 48 hours.

*930X XXXX XXXX (your Terva number)#

Check with your provider

An Optus home phone can only forward every call, not just unanswered ones. For an office with 1 to 5 staff, ask Optus on 13 33 43 which services can forward unanswered calls.

Check with your provider

Optus doesn’t publish a busy code for home phones or offices with 1 to 5 staff. Ask Optus on 13 33 43.

For most practices, When no one answers already covers after hours because nobody picks up. Check that voicemail doesn’t answer first, and make a test call after closing.

Check with your provider

We couldn’t confirm that an Optus phone line can forward on a schedule. Ask Optus if you need one.

Ring time

Set the no-answer ring time to 15 seconds where you can. 10 to 20 seconds is fine. For a call queue, set the caller’s total wait to about 15 to 30 seconds.

Check with your provider

Optus doesn’t publish how to change the ring time on a landline. Ask Optus to set 15 seconds.

Check it works

From another phone, not one on your practice line, ring your practice number.
Don’t answer at the practice. Let it ring out.
Terva answers.
Do it again once after hours. If voicemail, or someone carrying the practice phone, answers first, the call won’t reach Terva.

Ringing your Terva number directly doesn’t test forwarding. To test When busy, keep another call going on the line first. Test the after-hours route after closing.

Someone else looks after your phones?

Copy this, fill in the [brackets] and send it. It has your Terva number once you enter it above.

Your phone company

Codes don’t work, the account holder has to ask, or the line runs through an adaptor or older phone system.

Request for your phone company

Hi, I’m [your name], the account holder for [practice name].

On our number [practice number], please turn on call forwarding when not answered, to 0X XXXX XXXX, after 15 seconds. Please don’t forward every call: our phones should ring first.

Please also: - turn off message bank (voicemail) on this number, or tell me how, so it doesn’t answer first - set this at your end, not on our phone system or adaptor box - keep the caller’s number showing on forwarded calls

What does a forwarded call cost on our plan, and how do I turn this off again? I authorise this change.

When it’s done, Terva will ring our number to check it works.

Thanks, [your name]

Good to know

On an Optus multiline office phone, your phone system maintainer sets this up with the same codes.

Optus bills the forwarded part of the call at your landline plan’s rates.
