gateway

Soon I could use a SIP to GSM gateway, because I'll need to make phone calls from Germany to a mobile phone in Czech Republik. Hence, I thought about implementing one.

Now, the questions are:

Does such a solution already exist (for a reasonable price)?
Is it possible to redirect a (voice) stream to a GSM connection with the available Android APIs (SDK or NDK)?

Ideas, suggestions, comments are highly welcome.
