Call your PBX from any phone, enter a PIN and make an outgoing call as if you were in the office.
Dial tone access (also called DISA) lets you call your PBX from any phone, enter a PIN code, and then dial out as if you were in the office. The person you call sees your business number.
It’s useful when you only have a personal or borrowed phone but need to call a customer from your company number.
Add it to your call flow
Section titled “Add it to your call flow”- Drag Dial tone access from the Accept, make and divert calls group onto the canvas and click the gear icon.

- Choose the Caller ID for outgoing calls. To limit how many calls can use it at once, choose a SIP trunk call plan (optional) and set the Number of channels.

To use it, call that number, enter the PIN code, then dial the number you want to call.
