Answers To Your Questions

We’re sure with such an amazing offer you’re going to have a few questions. Here are some of the most common.

How long does Shared Calling take to set up?

You can enable Shared Calling in your organization in less than half a day.

This includes all the Teams tenant configuration which can be done in PowerShell using a script provided.

The deployment of Callroute and PSTN activation into your tenant takes less than 5 minutes and is instantly available. 

Will this affect my existing Teams Phone solution?

No. You can continue to use your existing Microsoft Calling Plan or Operator Connect service for your regular calling capabilities.

You deploy Callroute Shared Calling as a separate service that only your Shared Calling users will use.

In which countries do you support Shared Calling?

At the moment, this offer is only available to UK customers or international customers that need local UK origination for shared calls.

Can I add more Shared Calling numbers?

Yes, you can choose any number from any UK area code as your Shared Calling and emergency call back number. 

Every additional number above the free number included will incur a £1 per month number rental fee.

How are calls charged?

All calls originate from the UK. This means that you’ll pay domestic call rates when calling UK destinations and international call rates for any other destination.

Call costs are rated based on their overall duration and calculated to the nearest second.

How can I control costs so I don't get an unexpected bill?

You can set your monthly balance limit so you’ll never exceed your pre-planned budget. You can adjust this at any time. Emergency calls are unaffected.

We don’t permit calls to premium rate destinations by default. However, you can set your own call restrictions in Teams to deny certain destinations of your choice.

How do I pay my bill?

You will be sent an invoice detailing call charges at the end of each calendar month. 

Payment will then be due on a NET30 basis.

What is included in your white glove / assisted setup?

To enable Shared Calling requires some Teams tenant configuration. This involves the configuration of an auto attendant and some policy settings for shared and emergency calling.

Currently, the procedure can only be performed in PowerShell.

It is quite simple to implement if you are adept at PowerShell yourself. However, if you’d prefer us to help you with this to get going, then we can provide the technical expertise to complete the setup for you.

This involves:

  • Creating of one auto attendant for call back purposes with dial by name capability.
  • Creation of a UK Shared Calling policy and Shared Calling routing policy along with voice routes and call restrictions.
  • Enablement of all users for Shared Calling.

Provided you grant us temporary Teams admin permission to your tenant, we can deploy shared calling for your organization on the same day of sign-up. The process takes less than half a day for any company of any size. 

Afterwards, we will show you how its been configured, how to maintain it and how to use the Callroute portal to activate / deactivate your users.

What about inbound calling and caller identity display?

Out of the box, you are provided with a free 0330 non-geographic number that you can attach to an auto attendant configured for Shared Calling.

When your Shared Calling users make an outbound call, the recipient will see the 0330 number presented as the caller identity.

If the recipient calls the number back, this is routed to your auto attendant and they can use directory search to find the user they need.
