I want to implement a poor man's answering service. I want to be able to have my SIP phone number as allocated by ipkall, to be answered by someone in another country ("THE SERVICE"). As of yet, I do not have any kind of outgoing capability, other than through google talk.
As I cannot count on always being able to use THE SERVICE and may have to change THE SERVICE to another entity, I need to be able to "take back" my number if necessary
As I will be advertising my SIP phone number, I cannot change it or my advertising will be wasted.
Is there a way to do this?
Thank you in advance.
