Using Pass Through calling couldn't be easier.

1. Insure that the ATA is set up as shown on the Installation page with the local phone line connected to the local phone network.

2. Call the VoIP phone number assigned to the Pass Through phone. From any phone line to access your ATA device.

3. The ATA device you are calling will automatically give you a high pitch sound (usually after 4 rings), that indicates that it is asking you for a password.
(Ask your technical support for your temporary password)
After entering the password, you will hear a dial tone. That is the local dial tone where your ATA device is located.

4. Dial the number just as though you were there locally.
