Defining the SIP account to register at the LANCOM VoIP
Router or at a PBX
A LANCOM VoIP Router located in your local network can function as a SIP
proxy for the VoIP terminal equipment in the network. Terminal devices such
as a LANCOM Advanced VoIP Client can then register locally at the LANCOM
VoIP Router. The SIP proxy handles the switching of calls to a public SIP
provider or to a VoIP PBX at a different site. Alternatively, the LANCOM VoIP
Router as a SIP gateway can perform the conversion to other telephone
networks (e.g. ISDN) itself.
To use a LANCOM VoIP Router for telephony, a corresponding account has
to be set up in the LANCOM Advanced VoIP Client. On the ' SIP accounts'
tab, use the Add button to create a new SIP account.
For the provider setting, leave the entry as 'Custom' and activate the new
account.
For the 'User ID' enter the internal telephone number to be used by
LANCOM Advanced VoIP Client for taking calls and, optionally, enter a
name for your phone under 'Description'; this name will be displayed on
the other phone at the other end of the connection.
With the button Details, open the dialog for the advanced settings and
enter the following data:
As the 'SIP proxy' and 'Registrar', the internal VoIP domain for your
LANCOM VoIP Router (default: 'internal') if this also acts as the DNS
server for the client, otherwise, the LAN IP address.
