A technique manages user authentication via common authentication framework circuitry. The technique involves receiving, by the common authentication framework circuitry, authentication requests from client devices of users belonging to multiple enterprises, the authentication requests including user identifiers identifying the users belonging to the multiple enterprises. The technique further involves accessing, by the common authentication framework circuitry, entries of an authentication policy database to select authentication policies for the authentication requests. Selection of the authentication policies is based at least in part on the user identifiers of the authentication requests. The technique further involves invoking, by the common authentication framework circuitry, authentication services in accordance with the selected authentication policies to perform user authentication operations in response to the authentication requests from the client devices.

In a push-to-talk communications network, a method of transmitting a message from a sending device to a set of receiving devices is disclosed. The method includes selecting the set of receiving devices from a contact list on the sending device, such that each of the receiving devices has an address on the contact list. The method also includes transmitting the message to a message server, wherein the sending device is coupled to the message server; storing the message within the message server; and assigning the message an identifier. The method further includes notifying the set of receiving devices that the message can be retrieved, wherein each of the set of receiving devices is coupled to the message server. Advantages of the invention include a standards-based solution that combines the flexibility of mobile messaging with the ease-of-use of voice.
