Hi, I am a tech here in Viaero and indeed we have confirmed this problem and we are working with Nokia (our switch provider) to fix this problem. Surprisingly enough that the Nokia switch have some issues while other network providers like Ericsson support it.

I will update this post as soon as we get this resolved. We just got our N900 for testing so we should have a better idea in the next few days or so.

By the way, this seems to be a phone and network combination since caller id works on any other phone except N900.

Thanks for your patience.

Regards,
