Note: I said SOMETIMES, i.e. it was fine last night that I could receive incoming calls, and then just now the incoming calls goes directly to VM, which I didn't activate. out-going calls, however, has no problems.
=================================================
device: obi100
canada freephoneline
router tplink ac3200, obi100 hard wired to router, sip alg was disabled in router.
Firmware Version: 1.3.0.2815
ISP Name: teksavvy cable 25/2
Computer OS: windows 7
I have been using obi100 for a while. it's been working fine, i.e. could receive incoming calls with no problem. And I did NOT do anything about the setup. then suddenly last week someday out of blue that the incoming calls went directly to VM, then after 2 days it worked fine, then after another day, it went to directly to VM again. it's like on and off randomly while during the whole period I didn't do anything to it.
when it first happened, I tried *73, same thing, went directly to Voice Mail. rebooted both obi100 and the router.
the green light in the middle keeps blinking, the power light is green and solid, the phone light is not on - when not making a call.
checked both cable and phone wire connections, also tried different cables and phone wires, make sure there's no hardware problem, still same thing. what's weird and annoying is it worked fine for a week and this morning for one call after I did what OBi said on its web, then next call went directly to VM again. could not pin down where the problem is.
please help, thank you.
