Merry Christmas! My obi100 was setup through obitak. It shows registered. In the first few minutes after reboot I could receive incoming calls. After that no rings just went to voice mail. I have no problem with calling out. I opened all ports FPL required in my router.
Sometimes these strange problems are caused by SIP ALG.

My old router does not have this functionality. But your concept is correct. It worked after I enabled the X_keepalive and related parameters. Thanks.

I'm glad to hear your problem is solved. I suggest you disable your port forwarding and see if your service still works. Port forwarding effectively disables your firewall, and is not required with good routers. You should not forward ports unless there is no other way to make things work.
Thank you Mango. I will try it later.

I am having the same problem with my OBi202 and Freephoneline. After disabling SIP ALG on my Netgear R7000 router and enabled X_KeepAliveEnable for FPL, incoming calls still intermittently failed to ring the phone and were sent to voice message. I am using Obihai firmware 3.0.1 (build:4822). Anything else you did to resolve your problem? How do you open all the ports for FPL?
