The following table describes the fields on the page.
Note: Resolve to External Address dial rule and local domains
The Resolve to external address dial rule action (see Add Dial Rule Dialog) doesn’t match against
domains that are considered local. If the list of domains is empty and all domains are considered local,
this dial rule action won’t match any dial string and can’t be used.
In some circumstances (depending on network topology and configuration), dialing loops can develop
if you don't restrict the RealPresence DMA system to specific domains.
Field Description
Add new local domain Enter a domain and click Add to add it to the Local domains list. IP
addresses (including IP addresses with the wildcard character) and domain
names are accepted.
Domain names must be valid and full domains, but you can replace a single
host label within a domain with the wildcard character to match multiple
subdomains. For instance:, *.mycompany.com matches:
eng.mycompany.com
fin.mycompany.com
And eng.*.mycompany.com matches:
eng.sanjose.mycompany.com
eng.austin.mycompany.com
Subdomains are not local if the domain is listed without a wildcard character.
For example, if the domain mycompany.com is entered without any other
mycompany domains, this would NOT match eng.mycompany.com.
Local domains The list of domains from which the system accepts registrations. Select a
domain and click Remove to remove it from the list. Click Restore Defaults
to remove all domains so that the system accepts registrations from any
domain.
Locally registered SIP endpoints
belong to every local domain
Specifies that call requests for locally registered SIP endpoints don’t have to
match the domain. For example, if there is an endpoint registered as
‘sip:johnsmith@1.1.1.1’ and this option is enabled, a call to
'sip:johnsmith@mycompany.com’ may be connected to that endpoint.
If this option is not selected, call requests must exactly match the URI of the
registered endpoint.
