About adding an overflow number to a Talk number
To provide for a better experience for callers, you can add an overflow phone number to each Talk line you've added (not including external numbers).
When a call is not answered by an agent, and voicemail is off, the call will be sent to the overflow number. This could be the number of an external support organization, or an on-call agent that you use outside of your normal business-hours, or during holidays.
Things to consider when you set up an overflow number include:
- When Talk sends a call to an overflow number that is not a Talk number, a Support ticket is created. This ticket contains the tag,call_overflow.
- When a call is sent to an overflow number that is a Talk number, a regular ticket with no tag is created.
- If recording is enabled for that number, any tickets created include a recording of the overflow call.
- Overflow calls are charged as normal calls, including recordings, when enabled.
- When a call is sent to an overflow number, the caller ID sent to the overflow number will be that of the original caller.
When voicemail in Talk is turned off, no overflow number is configured, and when no agents are available to take a call, Talk defaults to your configured voicemail-off greeting, and then disconnects the call.
If you want Talk to always send calls to the overflow number when they cannot be answered, seeAdding an overflow number.
If you want Talk to send calls to the overflow number depending on the business-hours you have configured, seeAdding an overflow number when business-hours are configured.

Hi, I like theOverflowoption but is it possible to configure it in a way, that only calls to a certain IVR group will be routed to the external phone number, not all calls we get if everyone is busy? Thank you
Hi Agnieszka Kulpinska,
If the group you are routing the call to has no agents in it, then overflow calling will automatically be active and will route the call to the external number. However you cannot parse by IVR route as it is set at the number level.
Thanks!

Hi, Jason. We were removing agents from one IVR-group to create the overflow for that particular IVR-line. Unfortunately,Overflowwas also done for the remaining 3 other IVR-groups we have, which wasn't ideal. We have in total 4 IVR-groups and we want to createOverflowfor only one of them. Is is possible? Thank you.
We are new to Zendesk, and overflow function looks exactly what we need. However, I do not see the overflow option in the UI.
HiSergey Kandaurov, which Talk plan are you on? If you take a look at the banners at the top of the article, you'll see which plans are supported by overflow calls. If you do have a supported plan, let me know and I'll open a support ticket on your behalf.
Yes, that's right. I've upgraded to the Professional plan, and now see the option on a separate tab.
Glad to hear that. Thanks for letting us know!
My company is looking to add weekend support for one department from the hours 8am-3 pm CST. With the overflow number, is there a way to set a schedule for that overflow number?
