TPG and iiNet call forwarding to Terva

Use this if your practice number is TPG Voice or iiNet NBN Phone (Netphone). Both are set up in your online account, not with dial codes. TPG BizPhone works differently, so ask TPG.

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

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

Turn off voicemail first

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

  1. If voicemail answers your line, turn it off in the same online account, or ask TPG or iiNet to, so it doesn’t answer 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.

TPG Voice

  1. Log in to My Account, open View NBN Digital Voice Service Account, then NBN Digital Voice Service Control Panel.

  2. Open Call Forwarding/Diverting and choose Divert if no reply.

  3. Enter your Terva number, set the delay to 15 seconds, and save.

iiNet NBN Phone

  1. Log in to Toolbox, open your VoIP service, then Settings.

  2. Turn on When not answered, enter your Terva number and select Update.

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.

TPG Voice lets you set the no-reply delay between 4 and 39 seconds. Choose 15.

Check with your provider

iiNet doesn’t show a ring-time setting for NBN Phone. Ask iiNet if you need to change it.

Check it works

  1. From another phone, not one on your practice line, ring your practice number.
  2. Don’t answer at the practice. Let it ring out.
  3. Terva answers.
  4. 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.

Turn forwarding off

  1. Go back to the same page in your account and turn off each rule you set.

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

TPG and iiNet both charge their standard call rates for forwarded calls.
