SIP IVR voicemail

Creating a SIP IVR Voicemail box is easy. The recording from the caller can be delivered as an audio file to an email address of choice.

Sonetel phone numbers can be configured to send calls to Voice apps (SIP IVR). It is also possible to send calls from your SIP equipment to the unique SIP address of the SIP IVR voicemail.

A voicemail box has the following features:

  • Plays a message
    Plays a message prior to the recording “Welcome to XYZ. Please leave your message after the beep”.
  • Records the caller
    The recording continues until the caller hangs up.
  • Delivers the recorded message
    Sends the message to the destination of choice.
You can create as many voicemail boxes as you want. However, only phone numbers with business package or ones that are free with website or Premium can be connected to voicemail boxes.

To manage and configure your voicemail boxes, sign into the web app,  and click on the settings icon bottom left and then select Company settings -> Telephony -> Voice apps to see your voicemail boxes.

You can create as many new free voicemail boxes as you wish by clicking on the “+” icon.
