Abstract: A system and process for onboarding client devices to a key management server. In operation, a device generates an asymmetric key pair including a public key and a private key. The device obtains an access token from an identity management server after successfully authenticating with the identity management server. The device transmits a request including the access token and the public key to the key management server to onboard the client device. The device receives a response including encrypted bootstrap information from the key management server. The bootstrap information included in the response is encrypted using the public key of the asymmetric key pair. The device decrypts the encrypted bootstrap information using the private key of the asymmetric key pair to obtain the bootstrap information and then uses the bootstrap information for encrypting communications transmitted to the key management server or for decrypting communications received from the key management server.

Abstract: Techniques for variable length talk permit tone are provided. a request to initiate a Push-to-Talk (PTT) call may be received from a PTT call initiator. A first estimated length of time needed to set up resources for the PTT call may be determined. A second length of time to playout a talk permit tone (TPT) may be determined based on the determined first estimated length of time. An indication may be sent to the PTT call initiator to playout the TPT for the determined second length of time.
