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 Domains , 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.
