Abstract: The Session Initiation Protocol (SIP) is a highly flexible and extensible signalling protocol used in Internet (IP) telephony. As per the internet's nature, two peers engaged in a SIP session might not be from the same vendor, and/or might not implement the same set of capabilities and SIP extensions. For example, vendors might sometimes want to add or remove capabilities, as some implementations can be customized to fit the resources available to embedded devices, or the features required by the vendor's clients. This invention provides a flexible and easily extensible method of adding or removing the ability of understanding, accessing and creating certain SIP structures, at compile time.

Abstract: The Dynamic Host Control Protocol (DHCP) is a text-based protocol that functions over the Internet Protocol layer. The main use for this protocol i s to configure rebooting networking equipment. DHCP servers can assign dynamic IP addresses to DHCP clients from a pool of addresses, or can assign static addresses manually assigned by network administrators. Along with its assign ed IP address, a DHCP client is subject to receive a plethora of other useful configuration information. DHCP information, called options in DHCP lore, ar e typically registered with the IANA (Internet Assigned Numbers Authority), an d can have virtually any format for their data field. The present invention describes a generic way of adding new options of a DHCP client by specifying the data type for the option. This allows easy customization of DHCP clients . Typical examples of this optional information are the local subnet mask and the local router's IP address.
