6 Test purposes (TP)
6.1 Introduction
For each test requirement a Test Purpose (TP) is defined.
6.1.1 Test purpose (TP) naming convention
For each test requirement a Test Purpose (TP) is defined.
ETSI
12 ETSI TS 186 009-2 V2.1.1 (2009-03)
All test purposes belong to the main group ISUP_SIP_Interworking. Groups are organized according to the test suite
structure (TSS). Each test purpose is presented in a separate table. The first row of the table contains the following
items:
TP Identifier of the test purpose;
SIP reference the reference to the requirement in the DSS1 layer 3 Recommendation, which led to the TP;
ISUP reference the reference to the requirement in the interworking specification and the requirement in the
SIP-UP Recommendation, which led to the TP.
6.1.2 Source of test purpose definition
The test purposes have been developed based on ES 283 027 [1] as an endorsement of TS 129 163 [15].
6.1.3 Test purpose structure
The test purpose structure is according to the test suite structure (TSS).

Test purpose: SUT rejects unsupported media types

Ensure that If several media streams are contained in a single INVITE request, the
I-MGCF shall select one of the supported media streams, reserve the codec(s) for that
media stream, and reject the other media streams and unselected codecs in the SDP
answer, as detailed in RFC 3264 [18]. If supported audio media stream(s) and supported
non-audio media stream(s) are contained in a single INVITE request, an audio stream
should be selected.
