This is more of a curiosity and a thought than serious issue. But, I
wonder if I can get my Asterisk server to authenticate to my provider by
throwing the authentication requests to the SIP analog-adapter they
shipped me? (And I can't get in and see the authentication credentials
in the adapter, of course.)
In other words, say I've got something like:
SIP
analog adapter <--> * server <--> provider
Such that the DHCP and DNS information the SIP adapter gathers comes
from the asterisk server where it pretends to be the provider.
So then this happens:
- * tries to register with the provider
- gets the challenge
- the challenge is passed to the SIP adapter
- which answers the challenge correctly
- then * passes the answer to the provider and completes the registration
(AKA man-in-the-middle)
Is there such an authentication feature in *? If not, I could see it
being handy.
An alternative (although not as fun) would be to connect the analog
adapter to a FXO card in the * server.
PS- I know some providers could treat this as a violation to their
service agreement, btw.
