Methods and systems for receiving speed dial configuration changes may involve receiving a packet, determining whether the packet is associated with a valid command, determining whether a username in a header of the packet is a valid user, validating a signature using a public key, decrypting encrypted data using a first factor key, and executing the valid command associated with the decrypted data. The packet includes the header, encrypted data, and the signature, and is sent without a one-to-many management console and without prior group configuration. The validation of the signature may be based on the determination that the packet is associated with a valid command and that the username in the header of the packet is a valid user.
