ISO/IEC 29341-26-1:2017 PDF

Overview

ISO/IEC 29341-26-1:2017 - part of the ISO/IEC 29341 UPnP Device Architecture series - defines the Level 2 Telephony architecture for UPnP device control in home networks. The standard specifies an architectural model that enables UPnP Telephony devices, services and control points to be deployed in the home environment to manage incoming/outgoing calls, messaging, presence information and phone feature configuration using UPnP mechanisms. It describes the devices and services that can be embedded, their interactions, and deployment scenarios; it does not define gateway interfaces to non‑UPnP entities.

Key topics and technical requirements

• Telephony reference architecture and basic paradigms for UPnP Telephony.
• Devices and services definitions: outlines the logical UPnP Telephony Server, Telephony Control Point (TelCP), Telephony Client and related services.
• Call Management Service: call signaling, call state handling and control workflows (architecture-level description).
• Media Management Service: media path control, media negotiation and interaction with call management.
• Messaging and Presence services: message aggregation, presence subscriptions and presence state models.
• Supplementary services: calendar, address book, input configuration (InputConfig), and phone management via a data model.
• Security considerations: architectural view for authentication, access control and secure interactions within the home network.
• Deployment scenarios and diagrams: multiple physical/logical box models (2‑box, 3‑box), device co‑location and scaling examples.
• Normative aspects: terms, definitions, text conventions and references consistent with UPnP Device Architecture.

Note: the document includes patent declarations from multiple industry stakeholders; implementers should review those declarations when planning commercial products.

Practical applications

• Building interoperable home VoIP and telephony systems that integrate phones, TVs, media renderers and home gateways via UPnP.
• Enabling smart TVs, set‑top boxes and IP phones to act as telephony control points or clients for in‑home call management and messaging.
• Implementing device firmware, middleware or control point software that manages calls, presence and phone feature configuration over a UPnP-enabled LAN.
• Designing home‑automation solutions that incorporate telephony features (notifications, calendar integration, presence-aware routing).

Who should use this standard

• Device manufacturers (IP phones, smart TVs, gateways)
• Firmware and middleware developers implementing UPnP Telephony services
• System architects and integrators designing in‑home telephony solutions
• Interoperability test labs and QA teams validating UPnP telephony behavior
• Standards and compliance teams assessing product conformance
