Local Registrar

The SIP registrar keeps track of where a user is right now. The registrar receives registrations

from the SIP user clients and discards them when they become obsolete. A user can register

from several computers.

Here, you enter the SIP domains the Telecommuting Module should manage and set up

the SIP user database. If authentication should be used, you also need to do some settings

on the Authentication and Accounting page, and select which SIP methods should be

authenticated on the SIP Methods page.

If you want to use a RADIUS server for SIP users instead of a local database, you select that

on the Authentication and Accounting page.

Local SIP Domains

Here, you enter the domains that the SIP registrar should handle. Only users in these domains

can register on the Telecommuting Module.

Note that you should only list domains for which the users are expected to register on the

Telecommuting Module itself. SIP requests for other domains will be forwarded by the

Telecommuting Module to the server managing the domain in question.
