this is not tolerable.
if user A in one domain is able to call user B in another domain, i don't understand why it is not tolerable that user A sends a REFER to user B.
Imagine user_B uses a Linksys or any other deskphone (most of them allow incoming REFER without asking permission to the user).
- user_B@domain_B calls to PSTN number of domain_A. - Our OpenSer via ENUM query determines the target is user_A@domain_A. - The call is established. - Now user_A@domain_A sends a REFER with "Refer-to: 004598623435@domain_B". - user_B@domain_B phone is automatically referred to an internacional PSTN number via our OpenSer with no knowledge of user_B. - The international call is answered and tarified to domain_B account.
I do see a problem.
