Shale:
Look to the router.
Consider hooking the OBi directly to the modem temporarily for testing, if the router is not built into the modem. If that works, that would point to a router setting being the problem.
Also if you have SIP ALG settings in your router, try changing that... turn it off or on -- the opposite of what does not work.
You might have to get into port forwarding... I would search for others using your router to see what they had to do.
SteveInWA:
What he said....but, only turn SIP ALG off if it's on, not on if it's off. It's a useless feature for home networks. The one-way audio is usually a SIP port number, or firewall rule, or SIP ALG issue.

If that didn't fix it, I'd also suggest trying to isolate the OBi as the cause of the problem (or not) by installing a softphone client (like Counterpath X-Lite) on your computer (PC or Mac), configure it with your voip.ms credentials and see if that works.

Shale/Steve,
Thanks for help in trying to narrow this down. I have the ASUS RT-N56U router and have just updated the latest firmware added the feature to disable the SIP passthrough (currently enabled).
Previous to purchasing this Obi100, I was/am also using the Cisco Spa112 and it works fine. Could the router only affect the Obi and not the Cisco Spa112? Either way I am going to hook everything up again tomorrow and see what happens.
Thanks again!
SteveInWA:
If the same SIP credentials work on the Cisco SPA box, but not on the OBi, that obviously points the finger at the OBi. I don't use voip.ms. But, I found, with using Callcentric, that my SPA2102 ATA will work on different SIP ports, such as 5070, but the OBi would only work on the default port, 5060. If you have both devices trying to use 5060 at the same time on the same network, that could cause problems. YMMV, of course.
You said "SIP passthrough". We said, and we meant "SIP ALG". It looks like the ASUS router doesn't have a web GUI setting for this, and in fact the firmware messes up SIP, at least it did at the time this thread was written (I found it with a Google search on "asus router sip alg"):

Perhaps the firmware you downloaded adds this setting, but be careful to understand what it is actually doing. You do NOT want the router performing any management of SIP...so perhaps, if it says "passthrough", it should be ENabled. I guess this all goes back to what Shale said, you may have to try toggling it both ways if you can't find out how this relates to disabling ALG.

Tried disabling the SIP Passthrough option in the ASUS router with no luck. I then went directly from my cable modem to the Obi, verified that it got a proper IP address from my ISP and no luck there either, straight to voicemail and not registering as a call to the Obi at all.
