SIP
Production Test
Voice quality is not good:
The SIP phone supports packet loss and network jitter to some
extend. Above these levels, the quality can be bad. The G.729 codec will have better
performance over the G.711 codec and it can be selected in the configuration.
Call hold does not work properly:
The call-hold feature requires co-operation from both
ends. The behavior is not defined if the other phone does not support the hold feature.
Speakerphone does not work:
The SIP phone has a speaker to support one-touch
dialing, not for a speakerphone. The other party will hear you if you are in speaker
mode but the voice quality may not be good.

SIP
Production Test
This section describes the production test supported by the D-Link SIP phone. The
main hardware blocks to be tested are (i) LED, (ii) Key Scan, (iii) Hook Switch, (iv) Codec
& Handset, (v) Speaker, (vi) Memory and (vii) Ethernet MAC and PHY. If a test is
successful, the MGCP phone will play a
Success
tone and turn on the
Green
LED. If a
test fails, it will play an
Error
tone and turn on the
Red
LEDs. After each test, press ‘1’
for going on to the next test and ‘0’ for repeating the test again.
Note:
In some tests the SIP phone cannot determine the outcome of the test and the
user must verify it. In such test cases the phone will not play any tone.
