The following options will be available:
Edit VoIP Trunk Page Options
Option Description
Provider Name Enter a unique name to help you identify this trunk for use in
calling rules, etc.
Hostname The hostname or IP address assigned to the VoIP provider or
server.
Username/
Password You will need to provide your log on credentials to update your
service provider information.
Codecs Codecs provide the ability for your voice to be converted to a
digital signal and transmitted across the Internet. The quality of
your call can be affected by the choice you make. The codecs
available to you will depend on what is supported by the service
provider you choose. You can select the order in which the
codecs are used. The codecs commonly available are u-law,
a-law, GSM, G.726, G.722, and G.729A. A registered G.729A
license is required to use the G.729A codec.
Caller ID This is the number the trunk will try to use when making outbound
calls. For some providers it is not possible to set the CallerID with
this option. Thus this option may be ignored. When making
outbound calls the following rules are used to determine which
Caller ID is used, if they exist:
• The first Caller ID used is the Global CID defined in the Options
tab.
• The Caller ID set in the VoIP Trunks configuration, if defined,
takes precedence over the Global CID.
• The Caller ID set for the user making the call as defined in the
Users page will take precedence over the Global CID and the
CID set in VoIP trunks.
From Domain If required by your provider, specify your primary domain identity
to show in the domain field of the From header for outgoing SIP
invites. Otherwise, only your IP address will be sent in the From
header.
From User If required by your provider, specify the user to show in the user
field of the From header for outgoing SIP invites. Otherwise, only
your IP address will be sent in the From header.
Insecure This is a SIP parameter used to determine peer matching. The
setting determines whether or not an insecure connection will be
allowed, or if authentication is required. The valid options are:
• port - Enter this value to match against only an IP address. This
setting is useful if you have multiple endpoints behind a NAT
device.
• very - Specify this value if you do not want to require
authentication upon an initial invite.
• no - Specify this value if you do not want to allow an insecure
connection.
Enable Remote
MWI When you select this option, you enable voicemail from your
remote provider. Typically a user’s voicemail is stored locally on
the CSG. The notification of new voice mail is provided by the
same local CSG. If you would like to receive voicemail
notifications from a remote provider, this option is available. To
enable this option, click the check box, and in the Remote Mail
Box field, specify the remote mail box number or identity to which
you wish to subscribe, e.g. 6001. Select the local user who should
receive this MWI notification. Please note: enabling this option for
a local user will disable the local user’s CSG voice mail. It is not
possible to provide local voice mail and remote MWI
simultaneously.
