Obihai 202 Not registering Freephoneline.ca

[Sabbi]

Hi Everyone,

My Obihai202 is setup with two phones:
1) Google Voice
2) Freephoneline.ca

both were working fine for many years.

From last few days my Freephoneline.ca is showing not registering with the server.

Can someone suggest what could be the reason and how to fix this.

Thanks
Sabbi
