The techniques described herein may be used to provide a user with access to distinct applications (with Lightweight Directory Access Protocol (LDAP) authentication) based on a single set of user credentials from the user. A server may receive user credentials from a user device. The server may authenticate the user of the user device by communicating with an LDAP server. After the user has been authenticated, the server may detect a request from the user device to access a first application with LDAP authentication. The server may create temporary credentials for the user, provide the temporary credentials to the application, receive an authentication request (that includes the temporary credentials) from the application, and authenticate the user based on a local copy of the temporary credentials. If/when the user requests access to a second application, the server may authenticate the user for the second application in a similar manner.

System and method for applications to share single sign on through lightweight directory access protocol (LDAP) integration

A device in a provider network receives a Session Initiation Protocol (SIP) request message from an originating device, where the SIP request message includes a general number for a voicemail service and where the voicemail service includes multiple voicemail systems. The device determines whether the originating device is associated with a voice-over-Internet-protocol (VoIP) account on the provider network and, when the originating device is associated with a VoIP account, selects a direct access number assigned to a voicemail system, from the multiple voicemail systems in the network, that services the VoIP account. The device also associates the direct access number and the SIP request message, and forwards, based on the direct access number, the SIP request message to an application server.

On-net direct access to voicemail

A device receives, from a user device, a call destined for a call center, and provides an audio CAPTCHA (Completely Automated Public Turing test to Tell Computer and Humans Apart) to the user device in response to the call. The device also receives, from the user device, a response to the audio CAPTCHA, and determines whether the response is correct. The device forwards the call to the call center when the response is correct, and drops the call when the response is incorrect.
