Defining new device types
If you cannot find the device you wish to use listed in the default list, you can add several
device types.
¤
Select
new...
from the
Telephone Type
dropdown menu.
Configure the new device type n the
New Phone
dialogue window.
¤
Give the device type a unique name.
In the entry screen, the fields
type
,
dtmfmode
,
canreinvite
and
qualify
are preset and can
be applied in many cases. All other fields are not mandatory fields. Their importance is
explained in the following section.
Options for phone configuration
Please note
Usage of several codecs is subject to license G.729, for example, is integrated in
Gigaset T300 PRO / Gigaset T500 PRO, but must be registered first. The program for
this can be found in
/usr/lib/asterisk/modules/g729/
and is launched with the com-
mand
./register-g729-32-bit
.
type
The phone's connection type.
peer
Can receive calls via the Gigaset T300 PRO / Gigaset T500 PRO server.
user
Can instigate calls via the Gigaset T300 PRO / Gigaset T500 PRO server.
friend
A device that can both receive and instigate calls. This is the most com-
mon setting and advisable in most instances.
host
Use the
dynamic
option (instead of specifying an IP address), as sev-
eral device types can only log in with
dynamic
.
dtmfmode
Indicates the tone dialling standard that should be used. This is
dependent on the phone type being configured (see manufacturer's
specifications).
permit
IP address(es), via which the client can log on to the server. Either a
pure IP (e.g.,
192.168.0.1
) or IP/subnet mask (e.g.,
192.168.0.2/
255.255.255.0
). Multiple entries must be separated by commas.
deny
Is the opposite of
permit
and excludes the IP addresses specified here.
mask
If you have specified IP addresses without subnet masks under
permit
and
deny
, you can enter a single subnet mask (e.g.,
255.255.255.0
) for
both fields.
nat
yes
: If the phone is located outside of the LAN firewall, or
no
(default
value).
canreinvite
yes
provides clients with the option to exchange data directly (without
server involvement) after establishing a connection. As several hard-
ware components malfunction with this setting, the default value
no
should not be changed.
disallow
It is advisable to prohibit all codecs by specifying
all
and explicitly
allow the codecs of your choice by specifying these in the
allow
field.
The codecs must be entered as comma-separated values, e.g.,
alaw,ulaw
.
