Hi,
Besides the unlikely way of real roaming with an
carrier another option
would be to fake the outgoing number. Does anybody know a service that could
be used for that (i would need to fake a german GSM number).
I know some SIP providers (like voipbuster) let you set the outgoing
caller ID. However those (often ?) require to register that caller ID
first and prove ownership of the number in question (SMS / test calls
/ ...)
Does anybody know how this is handled on oil rigs or
ships? Do they have a
roaming agreement ?
On Waves ( http://www.on-waves.com/ ), the company that funded some
work on OpenBSC, does network on ships and they have "real" roaming
(SS7 connection / roaming agreements and everything AFAIK).
Cheers,
Sylvain
