When I call my cell phone from my Fongo number, my cell phone display the caller as "Unknown" . I noticed this sometime since 2011. I have tried to solve the issue by trying to reset my VOIP adapter (Linksys Sipura 1001) or reconfiguring the adapter according to the SIP settting indicated on my Fongo account. However the problem is still there. I wonder if there is a way to solve this? Thanks.
