You may find the history to be useful.
To check the call history log:
1. If you do not know the IP address of your OBi, find IP address:
from your phone dial ***1 and listen for the IP address. Write it
down.
2.Let a comma represent a pause. On your connected phone,
dial ***0,30#, 1, 1 (for OBi202 for first time to enable WAN web access).
For OBi100, 110, 200 or subsequent OBi202 access instead dial just ***1.
Your OBi should read your current IP number to you. It is often
192.168.__.__ or 10.0.__/.___ where __ represents some numbers. Write
that down.
3. Enter the IP address that you wrote down into the address box on your
browser. If you don't know what a browser is, that means Internet Explorer,
Chrome or Safari. It could also mean Firefox, etc.
Be prepared to enter the password for your OBi. The username is admin.
4. On the left, click Status -> Call History.
