[Freeswitch-users] Call redirect

[Steven Ayre]

It's all about Caller ID spoofing. If you are allowed to send anything you
could abuse that, and since there are plenty of services that use Caller ID
from the PSTN for authentication that could be a problem.

Wholesale carriers might allow it between themselves (trusted), but it
would be undesirable to allow it for end-users.

If you actually own the number (such as with DIDs) then that's a slightly
more specific case. If you could prove ownership to Y & Z and they had a
configurable whitelist then they might be able to add them to the list
since they can then trust you for those numbers, but they couldn't do that
for any random number you might send.

Proving ownership (and that you still own it) wouldn't be a very simple
task to handle securely though?
