You cannot control your network mailbox
Your handset supports inband DTMF sig-
nalling for controlling the network mail-
box. Some SIP providers require the use of
the G.711 or G.722 codec for remote con-
trol of the network mailbox. Therefore set
the handset's preferred codec if you expe-
rience control difficulties (page 89).

your SIP provider may not support inband
signalling.

Jabber servers offer gateways to other

The handset does not ring or playback of
the ringtone melody is poor
Possible causes:
u
The ringtone on the handset is deacti-
vated (Ú icon in the display, page 71).

back melodies in .WAV, .MIDI etc. formats.
However, optimum playback is not guar-
anteed for all melodies that you load onto
the handset. It may not be possible to play
back melodies at all.
The best playback results are achieved
with melodies that have been scanned at
max. 8 kHz.

Test playback with your one of your
own melodies.
You may be able to find a firmware update
on the Internet that will allow your hand-
set to provide optimum playback for melo-
dies scanned at a higher frequency.
