Thanks. I had to remove the auto-provisioning from my device and then edit the star codes and dial plan as that thread indicated. Then *86 worked.
Just as a suggestion to the Obi folks though, maybe they could set up their ObiTalk portal to remap these things automatically when a provider with a conflict (e.g. voip.ms
and callcentric) is chosen. If the whole point of configuring via the portal is to dumb things down and make the process easy for non-experts, it defeats the purpose if the person has to jump through a bunch of hoops in order to get something as fundamental as voicemail working.
I'm not trying to be critical at all... I know this product is just in its beginning stages and quite frankly I think it's awesome what Obi has been able to build into an ATA. Just more of a suggestion that if you're going to provide a wizard to configure the popular VOIP providers that you may want to at least make the end user aware of what won't work by default and maybe provide either a detailed how-to with screenshots or just devise a wizard to make the necessary changes.
Anyway, thanks again for the tip. Everything's working great now.
