SMS Caller ID

SMS Caller ID

If you have multiple SMS enabled phone numbers associated with your ReachUC account, you can now choose which phone number will be sent as the SMS Caller ID for outgoing messages.  You can view/change your SMS Caller ID from the SMS Numbers page of your ReachUC mobile app. This feature is only supported in the ReachUC mobile apps.  The ReachUC WebRTC (Windows and Mac desktop versions) will use the phone number you choose as your SMS Caller ID but you can not change this from the WebRTC applications.

Note: The Reply As setting found in the SMS Numbers Page will be able to override what number will be used as the SMS Caller ID for your replies.

Note: Creating new messages will always use your Primary SMS Number as the sender.

Viewing Your SMS Phone Numbers

In the SMS Numbers page, the My SMS Numbers section shows all the phone numbers assigned to your ReachUC account.  Here you will see a Primary icon beside the phone number which will be used as your SMS Caller ID when you send messages from any ReachUC application (including replies to SMS messages that are forwarded to an email address).

Note: If you have no phone numbers associated with your ReachUC account this will only show the text ‘No Numbers’.

Changing Your SMS Caller ID

From the list of phone numbers simply click on a phone number without the Primary icon beside it. Then click on Set as Primary in the menu that pop-ups at the bottom to change your SMS Caller ID to the phone number chosen.

Note: When adding an SMS number to your ReachUC PBX account, the default number will remain. However, when the phone number set as Primary is removed the oldest phone number added to your account will become your new SMS Caller ID and be marked as Primary.


The steps on an Android or iOS device are similar:

  1. Open the PBX pane.
  2. Go to the PBX Account tab.
  3. Open the SMS Numbers page.
  4. Click on the desired number listed under My SMS Numbers.
  5. Click on Set as Primary in the menu the pop-ups at the bottom.

The Sections in the SMS Numbers Page:

2 – Reply As

This shows the behavior of what phone number is used when you reply to messages in ReachUC. Clicking here will show you the choices available with your current setting having a checkmark icon beside it. Clicking on the choice with no checkmark icon will change your setting to the choice you clicked.  The choices are either Primary SMS Number or Smart Source.

Primary SMS Number is the default setting which if used means that all replies coming from your ReachUC app will use your chosen Primary SMS Number.

Smart Source is the setting that will use the last phone number having a conversation with the recipient, however, if there is none it will use your Primary SMS Number. Note: This settings’ behavior will also apply to your WebRTC applications.


3 – Number Sharing

Clicking on Number Sharing will open the page to view the phone numbers that have been shared with you, and also your phone numbers which are available to share with other ReachUC Users, and lastly, any shares that you have set.  SMS Number Sharing is the ability for those who you shared your number with to reply to any message you receive as though they were using your phone number.
