Show your contacts who's calling.
Sigma Voice is a leading service provider of 'one-to-many' automated calling and mass texting.
There are 2 parts to the Caller ID Display.
You may use your own office phone number or mobile phone number.
Please note that the Caller ID must be a valid working phone number.
The Caller Name cannot be set within our system.
However, our system will display the Caller Name associated with the Caller ID used.
For example, if you make a phone call with your mobile phone, your phone number and name associated with your phone will be displayed to your contact.
If you use your mobile phone number as the Caller ID in your Sigma Voice automated call broadcast, your phone number and name will be displayed on the phones you are calling.
The Caller ID can be set to a virtual phone number for call tracking purposes.
Caller ID spoofing is when a caller deliberately falsifies the information transmitted to your caller ID display to disguise their identity.
This is not allowed on the Sigma Voice platform.

Sigma Voice was so easy to set up. I needed to get an immediate message out to my 60+ family members. It’s affordable, the reports are amazing, and the customer service is beyond what I expected on a Sunday afternoon. Highly recommended!
