It does sound like the unit resets in this case.
We would like to debug this case for you.
Could you email to
support@obihai.com and provide the following information:
1. Your OBi number (on the back of the unit)
2. Some more details about your setup:
- What service providers are configured on SP1 and SP2?
Are they Google Voice or something else?
- Are you able to call the forward number on SP1 from your
phone? That is, dial **1123456789 from phone to ring it?
Try also upgrading your unit to the latest firmware version (posted on
obitalk.com)
to see if it fixes the problem.
I also strongly recommend you to sign up for an OBITALK account if you haven't done so already. That will allow us to push firmware to your unit and perform other trouble shooting steps.
