By using the 'Sticky Caller ID' feature you can set up smrtPhone to automatically assign as the Caller ID the last number that was used to communicate with a certain contact when placing an outbound call. That means if someone calls in on a number, when we dial back we will automatically use the same number, regardless of any geo-caller id rules.
In order to set up a 'Sticky Caller ID' feature for your users, all you need to do is to head over to Admin -> Users and to press the settings icon located near the name of the user.
For each member of your account, you wish to enable the 'Sticky Caller ID' feature, click on the 'Settings' Icon. You will be presented with the configuration settings for that user.
The 'Sticky Caller ID' feature increases call to pick up by automatically selecting the best number for outbound dialing.
Note: Only the admins of the account can enable/disable the Sticky Caller ID feature for the members of the account.
