Wireless networks and the voice over Internet protocol (VoIP) have recently been widely adapted. VoIP services over Ad-hoc network can be accomplished by middleware embedded in mobile devices. In this study, we have implemented an intelligent VoIP system with embedded pseudo session initiation protocol (SIP) server in an Ad-hoc network. We employed the standard SIP protocol and integrated SIP p...

Session Initiation Protocol (SIP) is a new signaling protocol designed to establish multimedia sessions in telecommunication networks. In this paper, we suggest the extension of SIP functionalities to coordinate QoS mechanisms deployed in IP networks, and especially in DiffServ domain. Indeed, the interaction between small and big TCP sessions may have dramatic consequences on small TCP session...

In the session initiation protocol (SIP), payments have been proposed as a way for vendors to obtain profit from the services they provide. Payments in SIP have also been proposed for microbilling and even as a solution to SPAM in VoIP systems. Although several proposals exist for making payments in SIP, they present some limitations when we want to pay for access to real-time services: either ...

This document introduces the transport of call control User-to-User Information (UUI) using the Session Initiation Protocol (SIP) and develops several requirements for a new SIP mechanism. Some SIP sessions are established by or related to a non-SIP application. This application may have information that needs to be transported between the SIP User Agents during session establishment. In additi...

The Session Initiation Protocol (SIP) is often used to initiate connections to applications such as voicemail or interactive voice recognition systems. This specification describes a convention for forming SIP service URIs that request particular services based on redirecting targets from such applications. Jennings, et al.

This paper presents a software prototype of wireless network for the Internet Things (IoT) based on DECT (Digital Enhanced Cordless Telecommunication) standard. It proposes an architecture encapsulating commands from most common IoT protocol, MQTT (Message Queuing Telemetry Transport), into SIP (Session Initiation Protocol) packets. A module is created to embed MQTT-SN (MQTT Sensor Networks) pa...

session initiation protocol (sip) is the main signaling protocol of next generation networks (ngn). sip based applications are usually deployed over the internet, for which their text-based nature and internal stateful operation make them vulnerable to different types of attacks. the real‑time functionality of sip based applications make their related security systems more complex. on the other...

This document defines a new header for use with Session Initiation Protocol (SIP) multi-party applications and call control. The Replaces header is used to logically replace an existing SIP dialog with a new SIP dialog. This primitive can be used to enable a variety of features, for example: "Attended Transfer" and "Call Pickup". Note that the definition of these example features is nonnormative.
