uc mobile for iphone

[marcustherock]

just want to get some feedback and ideas regarding uc mobile for iphone.....
i have mas v4 with all blades installed, running on a single server on edge mode.
i am able to register a blackberry with UC but not an Iphone....
i have tested both accounts on BB and it works, any ideas or settings that could be specific?

Thanks

Have you run the TNA tool to check that all the required ports are open?

Also in one instance before I have had to configure a couple of extra ports to be forwarded for an android to be able to work. They didn't have any iphones though so not sure if it applies to them as well.
