A device may receive, from a network device, a resolution query associated with a call. The resolution query may include a device identifier of the network device. The network device may receive, from a user device, the call. The device may determine, based on the device identifier of the network device, whether an authentication condition is satisfied. The device may selectively provide, to the network device, an authentication token in association with the resolution query based on determining whether the authentication condition is satisfied. The authentication token may enable an endpoint device, associated with the call, to perform a particular action based on the call.

Network based call authentication

AIN based methods and apparatus for authenticating and authorizing people to register information corresponding to a telephone number, e.g., in an ENUM database, are described. The methods of the invention may be used to authenticate a party seeking to register telephone number related information with ENUM. A trigger is set on an ENUM registration line. Calls to the ENUM registration line activate the trigger causing LIDB information corresponding to the calling party number to be retrieved. The retrieved information, e.g., name, address and/or phone number is supplied to an ENUM registration service which returns a password to be used when updating or supplying ENUM registration information corresponding to the phone number from which the registration call is placed at some future time, e.g., via the Internet. Assigned ENUM passwords can be obtained when forgotten by placing a call to the registration service from the registered or associated phone number.

Methods and apparatus for authenticating and authorizing ENUM registrants

A device receives a Session Initiation Protocol (SIP) response that includes a load header associated with a downstream Session Initiation Protocol (SIP) device. The device also determines an amount of traffic to send to the downstream Session Initiation Protocol (SIP) device based on the load header. The device further sends the determined amount of traffic to the downstream Session Initiation Protocol (SIP) device.
