Hi, thanks to Greg's patch, new functionalities are available in the enum module. Here is the initial description of the patch: <quote> is_from_user_enum: I find this extremely useful. This function uses the 'From' uri and does a enum lookup based on that number. A true or false is returned. I route to my customers using enum, so when the customer does an outbound call i can use this to verify that they are indeed a valid customer before routing the call. enum_fquery: Carry the previous function another step. You can do 'source routing' of a call using the from address. I do a enum lookup based on the from number, and then apply the ruri to number to the naptr that was found. Using this technique you can 'source route' individual numbers. In this way, for example, customer A can elect (pay for) routing out 2 or 3 gateways, while customer B elects to just have one provider. Another interesting feature is to temporarily reroute a customer to an intercept stating that his account is suspended. </quote> for details, please refer to the on-line documentation: http://openser.org/docs/modules/1.1.x/enum.html regards, bogdan
