This has always been one of my pet peeves, even as I worked in the industry. A telco switch operating a DS1 on trunk side should enforce caller-id numbers to be within the range of DID numbers assigned to that trunk. There should be a default DID number that is used to replace any *invalid* numbers sent on that trunk. Note that blocked caller ids would still be blocked, but the rest of the data should be corrected. Blocking ID is ok, lying about it is not.
Blind trust of a non-SS7 link is a _bad_ thing. ==================================================================== Timothy R.

Calling the customer on the provided number(s) would be an easy way to check, and a setup fee could be levied to cover the provider's time and expenses, if required. Being able to discover a "blocked" Caller*ID is another matter. Both are good areas for regulation. -- _/ _/ _/_/_/_/ _/ _/ _/_/_/ _/ _/ _/_/_/ _/_/ _/ _/ _/ _/_/ _/ K e v i n W a l s h _/ _/ _/ _/ _/ _/ _/ _/_/ [EMAIL PROTECTED] _/ _/ _/_/_/_/ _/ _/_/_/ _/ _/ _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
