Registrations), and to forward all requests addressed to a specific SIP domain to a SIP
server (DNS Override For SIP Requests).
You can also configure how incoming calls for local SIP users should be processed. You can
restrict allowed callers and send the calls on to a voice mail server.
You can also select to process class 3xx messages in the Telecommuting Module or pass
them on to the client.
When the Advanced SIP Routing module is not installed, this page presents only limited
functionality.
DNS Override For SIP Requests
Here, you can register SIP domains to which the Telecommuting Module should be able to
forward requests, but which for some reason cannot be resolved in DNS. Enter an IP address
and port to which the requests should be forwarded. You can also select to use a specific
protocol.
The Telecommuting Module uses the Request-URI of the incoming SIP packet to match for
the domains in this table. When it matches a domain, the packet will be forwarded to the IP
address entered here. Note that the Request-URI will not be rewritten!
You can also enter subdomains to Local SIP Domains, if you want the subdomain to be
handled by a separate SIP proxy. This table has a higher priority than Local SIP Domains,
which means that if you register a subdomain to a domain registered under Local SIP Do-
mains, the Telecommuting Module will forward SIP requests to the subdomain instead of
processing them itself.
You can enter more than one IP address or host name for a domain, and set weights and
priorities for these.
Domain
Enter the domain name of the SIP domain. This domain is compared to the domain in the
Request-URI of the incoming SIP packet.
You can’t enter a domain that was entered in the Local SIP Domains table.
