Setting up

Send your calls to Marble Song.

Your Marble Song number arrived by email. The last step is telling your phone when to hand calls over to it. It takes about three minutes, there's nothing to install, and you can undo it at any time.

What do you want us to answer?

Most owners choose "only the calls I miss". It works like a much smarter voicemail: you keep answering calls yourself whenever you can, and anything you don't pick up comes to us instead of going to a beep. Choose "every call" if you want all of your calls to come to us. One more thing in favor of "only the calls I miss": your phone rings first, and many automated dialers give up before the call ever reaches your assistant.

From your welcome email. Fill this in and we'll write the exact code out for you. It stays in your browser — we don't receive it or save it.

Then test it

From a different phone, call your business number and let it ring without answering. If you set up "only the calls I miss," give it a good four or five rings. You should hear the Marble Song greeting. You'll also get a summary afterward, which is a second confirmation that the whole path works end to end.

If you hear your own voicemail instead, the forwarding setup didn't work. Email us and we'll work it out with you.

Things that will switch forwarding off

Forwarding lives on your carrier's network, not on your phone, and these events will clear your forwarding settings it without telling you:

If any of those happen, come back to this page and set forwarding up again, then re-test. It's worth re-testing every month or so regardless — it takes thirty seconds.

If something doesn't match

Carriers change these codes and menus, and some plans — particularly prepaid and some business plans — restrict call forwarding or require an account administrator to switch it on. If what you see on your phone doesn't match what's above, or a code comes back with an error, don't keep guessing: email [email protected] and tell us your carrier and phone. We'll sort it out and correct this page.

Forwarded calls may count against your plan's minutes or carry a charge from your carrier, depending on your plan. Most current unlimited plans include domestic forwarding at no extra cost. Instructions last verified .
