TIA Updates Suite of Standards on VoIP Supplementary Services Descriptions

Standards Series Addresses Wireless Features Likely to Be Used When Roaming and Features Necessary to Implement Full Intersystem Operation

Arlington, Va. – The Telecommunications Industry Association (TIA), the leader in advocacy, standards development, business development and intelligence for the information and communications technology (ICT) industry, recently updated several standards in the TIA-1126 Voice over Internet Protocol (VoIP) Supplementary Services Descriptions series.

The updated standards are:

• TIA-1126.553 Customized Ring Back Tone
• TIA-1126.554 Directory Assistance
• TIA-1126.555 Inbound Call Restriction/Anonymous Call Rejection 
• TIA-1126.556 Outbound Call Restriction
• TIA-1126.558 Terminating Identification Presentation
• TIA-1126.559 Terminating Identification Restriction 
• TIA-1126.562 Voice Message Retrieval

TIA-1126 contains the description of supplementary telecommunication services in the Multi-Media Domain system. Its intent is to describe services and features so that the manner in which a user places calls using such features and services may remain reasonably consistent from system to system. TIA-1126 does not require specific service offerings of all service providers. A service provider may offer all or a subset of these supplementary services.

This series describes a set of wireless features, which enable their use in any system on which the user roams. To accomplish this, the TIA-1126 standards set consists of features that are likely to be used when roaming, and also features necessary to implement full intersystem operation.

Due to the nature of IP-based telecommunications, and the associated improvements in the network capabilities, there are some deviations from the circuit-switched equivalents. The goal of the TIA-1126 series is to achieve service consistency between Circuit-Switched wireless systems and Packet-Switched systems without unduly restricting possible improvements that may be feasible in VoIP.

The TIA-1126 suite was formulated under the cognizance of the TIA Engineering Committee TR-45 Mobile & Personal Communications Systems, TR-45.2 Subcommittee on Wireless Intersystem Technology.
