You have the possibility to make and receive your calls only in VOIP provided that the country where the call is made or received, does not block VOIP

With Onoff, you only pay for what you use. If you take a number in the middle of the month for example, you will only pay in proportion to this period only.

Every time that you or your employees interact with any of your CRM contacts (either by making/receiving a call, or sending/receiving an SMS), our integration will automatically fetch the latest data from the CRM and create a new contact in the Onoff platform (for non existing contacts). This will allow Onoff users to get valuable contact information directly in the Onoff interfaces: see CRM details in the Contact's details, get CRM results when searching for a contact/number in the dialpad, enhanced CallerID for your incoming calls, etc.
Plus, in addition to automatic contact creation, users can manually update the information for existing Onoff contacts inside the contact details. This specific action will replace the existing information for the Onoff contact with the latest data from the CRM.

If you experience issues logging calls, SMS or VM in your CRM, please make sure that all the necessary conditions are met:
-The Onoff Business administrator of your company already set up the integration, and the integration is currently active
-Your Onoff number is enabled to sync with the integration, if you have doubts check with your admin
-The interaction (call/SMS/VM) involved a Contact or a Lead existing in your CRM. Make sure that the contact was registered in the CRM with a phone number in the proper format (we support phone numbers in international format only, i.e., including the country code, example: '+33 6 xx xx xx xx' and not '06 xx xx xx xx') or else no data will be logged in the CRM.

If all conditions are met but the issue persists, don't hesitate to reach out to our support team

The CRM integration is included from the Advanced offer.

Yes, when you use the Onoff Business chrome extension to make calls, or to send SMS to your CRM contacts, all these interactions will be automatically logged in the Contact's timeline.
Please note that if the call or SMS happened before the integration was set up or the contact was created in the CRM, the interaction won't be automatically logged.
We don't create contacts in your CRM automatically, as to avoid polluting your CRM's contact base.

Yes, when you use MS Teams to make calls, or to send SMS to your CRM contacts, all these interactions will be automatically logged in the Contact's timeline.

We don't create contacts in your CRM automatically, as to avoid polluting your CRM's contact base.
Also note that currently Voicemails are not recorded in the call logs.

There will be times where the info displayed might not be updated immediately. In these cases, you can wait 5-10 minutes and then refresh your page.

When an event needs to be logged in the CRM, we will search for the email address of the Onoff Business user among all CRM users. If we find a match, then the event (call/SMS/VM) will be logged in the CRM and assigned to the corresponding user. For example if the Onoff Business account is [email protected] and the crm account is [email protected] > then the calls/SMS/VM related to Marie's number will be logged and assigned to Marie.
If there is no match, then the event will be created and assigned to the current contact owner.
Otherwise, if the contact doesn't have an owner, the event will be logged but will remain un-assigned.

"Greeting" is a "standard number" which allows you to transfer your incoming calls, in cascade or simultaneously, it is also possible to reallocate a number from one user to another.
