Abstract
This document describes the requirements for SIP telephony devices,
based on the deployment experience of large numbers of SIP phones and
PC clients using different implementations in various networks. The
objectives of the requirements are a well-defined set of
interoperability and multi-vendor-supported core features, so as to
enable similar ease of purchase, installation, and operation as found
for PCs, PDAs, analog feature phones or mobile phones.
We present a glossary of the most common settings and some of the
more widely used values for some settings.
