Brought a 100 up on a voip.ms account for a friend.

A) Got nailed with the silent caller flood a few hours later. http://wiki.voip.ms/article/OBi_100/110_%26_OBi_200#Settings_to_avoid_direct_phone_calls_to_your_device_in_the_middle_of_the_night offered several suggestions.

Is there some reason to prefer one approach over another?


B) voip.ms's instructions tell you to disable the Obi-Obi 9-digit ObiTalk function. Is it incompatible with PSTN usage with voip.ms?  This person actually used it.

I use the latter approach [ {>('100000'):ph} ] since it is all-encompassing.  On more recent firmware loads, though (at least on the OBi200 series boxes), there is an option

Voice Services -> SPX Service -> X_AcceptSipFromRegistrarOnly

that I believe accomplishes this more succinctly.

I regularly use both voip.ms and the OBi-to-OBi direct 9-digit dialing on my box and have never had a problem with either interfering with the other.  If you are seeing the above attacks, though, your box is probably not sitting behind a NAT-protected router, and as such, your OBiTalk interface may also be susceptible to these types of injection attacks.  YMMV.
