To make a port that currently has an extension assigned to it available for dynamic
login, first unassign the extension from the port, resulting in a free extension and a
free port.
Note: In order to log in dynamically to a free device using a free extension, the
extension must have a user pin configured.
3.7.6 Configuring SIP extensions
In addition to the basic and advanced configurations (please see 3.7.6), SIP
extensions also allow the configuration of various voice codecs in order to provide
compatibility with SIP providers and phones.
Codecs supported by a SIP extension can be selected by using the Codecs button.
Use Ctrl-Left-Click (holding Ctrl down) to select multiple codecs. Individual codecs
can be moved up and down the codec priority list by selecting the codec entry, and
selecting the Up or Down buttons. Codecs may specify the integration time in
milliseconds after the codec name in the form codec:integrationtime, e.g. 'g729:40'
When negotiating a SIP call, the codec with the highest priority(at the top of the list)
will be attempted first, then the second and so on.
3.7.7 Remote SIP extensions
When configuring SIP extensions as remote extensions at a remote site (e.g. home
ADSL), if the Com.X is located behind a NAT/firewall on the network, configure the
NAT/firewall to forward UDP port 5060 to the Com.X internal IP address. If required
(no NAT available), also forwards RTP ports 10000-20000 to the Com.X internal IP
address.
You may also need to configure the external address on the Com.X by selecting Start
-> Configuration -> Setup and then setting the External address. Configure this field
to the dynamic DNS name or the FQDN that resolves to the external (public) address
of the Com.X (i.e. the external address should be set to the same as will be
programmed into the remote phone).
If you are using dynamic DNS, make sure that the External Is Dynamic field is set to
true.
3.7.8 Assigning extensions
Free extensions can be assigned to a port by editing the extension, and selecting the
Port button. From there a menu of available extension ports can be accessed. Only
available ports are listed in the menus.
Alternatively, drag a free port onto a free extension in the Extensions panel.
3.7.9 Unassigning extensions
Extensions' associations with ports can be removed by selecting the extension in the
extensions list, and selecting Unassign from its context menu (right-click.)
