I am trying to explain my issue as clearly as I can.
I bought two OBI 200 a few years ago, one was set up with Phone, and the other was set up with Fax, both worked fine when setting up a few years ago.
Obi 200 linked to phone: It works fine all the time during the past few years. I use the phone regularly.
Obi 200 linked to fax machine (actually a printer with fax feature): When it was set up, it worked, but I don't know when it stopped working, since I almost never use fax. Recently, I transferred this Google Voice number to another google account, so the device OBI 200 has not been added to new google account. However, I think it stopped working way before I transferred Google Voice number. Anyway, I am trying to connect this OBI200 to the fax machine again, it just does not work (no matter how I dial ** 5 #### from fax machine, #### is randomly four ending digits generated by system).
I switched internet cable and phone cable between these two OBI devices, fax is still not working, phone is still working, so there is no issue with internet cable or phone cable.
Now below is video link on Google Drive, OBI 200(linked to fax) Phone LED keeps blinking green, I mean the LED on the right. While OBI 200 (linked to phone) Phone LED is solid green.
What is the issue here? Is the OBI device broke?
Thanks.
