Audio feature interactions in Voice-over-IP

ABSTRACT

In telecommunications, audio signaling is the use of the audio channel for signaling and user-interface purposes. When features use audio signaling, and are assembled in a pipes-and-filters configuration, there is a potential for undesirable feature interactions. This paper analyzes the potential feature interactions. It proposes a method for eliminating some of them, as well as directions for future work on the remaining interactions. The method can be implemented in SIP, using compositional patterns of signaling that will work correctly regardless of how many features are active.
