When I sign up with a provider to get minutes and a phone numbers (also Known as a DID, I believe - please correct me if I am wrong) for my phones I am stuck with them because I do not own the phone numbers they give me. I have read that the provider is the actual ‘customer’ and owns the telephone number, and they are just loaning it to me.
As one of Asterisk’s features, it allows you to change providers rather easily in a config file, ensuring that you aren’t locked into any one provider. If the origination/termination provider actually owns the number, how can I simply move to another without changing numbers? This would be a big problem if you had already advertised your phone number and the provider raises the rate of their service.
How do you all handle this? Can you give me any suggestions, tips or advice?
