Automated Failover

Automatically re-route on failure detection

How it works

What gets monitored gets protected. By monitoring your phone system connection 24/7, calls automatically divert to pre-configured destinations if there’s a break in service. Once the fault has been resolved, your service is restored immediately.

Set secondary destinations for incoming calls

Add your user’s cell phone or your customer services phone number as a secondary destination incase Teams fails.

When Teams is offline, callers are automatically diverted to the selected fallback destination.

Automated Failover FAQs

Will active calls be automatically reconnected to my failover number?

If you experience a phone system outage while on an active call, the call will disconnect.

Unfortunately, we are unable to automatically redial the caller into your failover service. However, they can call back and will immediately be diverted to your backup service.

Does it cost me anything to divert to my backup service?

 If this service is an external service e.g. mobile number then normal call charges will apply for the duration of the call. If you have a Callroute calling plan, these calls will be deducted from your remaining minute balance.

If your backup service is another phone system connected to Callroute, such as a PBX, then there is no additional cost while using the failover service.

What will trigger automatic failover?

When we route a call to your phone system, we are looking for an acceptance message. If the acceptance message is not received or your phone system responds with a 4XX or 5XX SIP response error code, we treat this as a failure and will failover to your backup service automatically.

More information on SIP response codes can be found here

Can I disable automatic failover?

Once a secondary destination has been set for a user, it is active and cannot be selectively disabled. However, you can choose to remove the destination and reapply it at any time to re-enable the service.

My AzureAD contact information is not up to date. How will this affect failover?

AzureAD synchronization for automated failover can be administratively disabled or enabled.

You will need to perform an internal housekeeping task to sanitize your AzureAD information before enabling the sync to avoid problems during failover. AzureAD is the source of authority for this information when enabled and as a result must be accurately maintained.

Can I override AzureAD synchronization?

Yes. As an administrator, you can reconfigure any failover destination for any number.

Are there any limitations?

For automatic failover to work, calls must transit the Callroute network. If you are using BYOC or Callroute Calling Plans there are no limitations of use.

We do not support automated failover for users with Microsoft Calling Plans or Operator Connect because Callroute is not party to the voice path. However, should these services fail, depending on the severity and urgency, you can reconfigure users to use Callroute temporarily.
