    摘要: In accordance with a particular embodiment of the present invention, a method using shared configuration information to manage network access for externally generated communications includes maintaining association information for a first end user of a private network and maintaining configuration information for a first endpoint associated with the first end user. When an externally generated communication that is addressed for delivery to a second endpoint associated with a second end user is received at an access point to the private network, the association information is used to determine an association between the first end user and the second end user. The configuration information for the first end user is used to configure the access point to allow the communication to be delivered to the second endpoint.

    摘要: A VoIP call routing information registry including a hash access mechanism. In particular implementations, a method includes receiving a telephone number; computing a hash of the telephone number; accessing a registry wherein the registry comprises a plurality of entries, and wherein each entry comprises a hash of a telephone number and data associated with that telephone number, or a prefix and data associated with that prefix; searching the registry for a matching entry; and until a matching entry is found or the telephone number has been stripped down to a minimum number of digits, stripping the last digit of the telephone number, re-computing a hash of the stripped-down telephone number, and re-searching the registry for a matching entry.

    摘要: An authentication agent may cryptographically identify a remote endpoint that sent a media initialization message even though intermediate devices may modify certain fields in the message after a signature is inserted. The originating endpoint's agent may create the signature over some fields of the message using an enterprise network's private key. The agent may insert the signature into the message and send the message to a recipient endpoint's authentication agent. The recipient agent may verify the signature, receive a certificate including a second public key, and challenge the identity of the originating endpoint in order to confirm that identity. This challenge may request a confirmation that the originating endpoint knows the private key corresponding to the second public key and may occur while running encrypted media at the endpoints. After the originating endpoint is authenticated, the endpoints may exchange encrypted and/or unencrypted media.

    摘要: Techniques are described for the use of a cryptographic token to authorize a firewall to open a pinhole which permits certain network traffic to traverse firewalls. An initiating endpoint requests a token from a call controller, which authorizes a pinhole though the firewall. In response, the call controller may generate a cryptographic authorization token (CAT) sent towards the destination endpoint. The call controller may generate the token based on an authorization ID associated with the call controller, a shared secret known to both the call controller and the firewall, and data specific to the media flow for which authorization is requested.

    摘要: In accordance with a particular embodiment of the present invention, a method using presence information to manage network access includes maintaining presence information for an end user. When a remote access request is received from the end user at a remote endpoint, the presence information for the end user is updated to identify the presence of the end user at one or more network endpoints associated with a private network. An access point to the private network is then automatically configured to allow any communications addressed to an IP address associated with the one or more network endpoints to pass through the access point.

    摘要: A system for sharing presence-based time-zone information includes a database, and a controller. The database includes a plurality of presence profiles, each presence profile maintaining, for an associated network user, one or more network device identifiers and, for each network device identifier, a current presence status, indicating network availability, and current time-zone information based on geographic location. The controller is able to receive presence information, determine a matching one of the presence profiles, update the current presence status and the current time-zone information in the matching one of the presence profiles, generate shifted time-zone information, generate a presence update, identify a subscriber address for receiving the presence update, and transmit the presence update to the subscriber address.
