The call routing table suggested by the setup wizard automatically allows
spontaneous outside line access for ISDN and SIP users
and
.
As a result of both of these routes, any stars '*' that might have preceded
the numbers are removed before each call from a local user. For all other
calls from local users, the number is preceded with a '0', as it is automat-
ically assumed that the user is trying to establish an outside connection.
The other routes are used to carry out international
and national
long distance calls as well as local calls
as standard over the ISDN line.
The Call Router removes the preceding zeros from the number again and
sends the call out to the ISDN line.
In order to channel calls to special destinations, such as international and
national long distance calls, over the SIP provider and not over ISDN, dou-
ble-click on the corresponding entry in the table and switch the line used
form 'ISDN' to 'SIPPROVIDER'. Don't forget to switch the backup line from
SIP to ISDN, if necessary!
Routes for spontaneous outside line access
Entering the source line 'USER' is not visible in the screenshot. Using this filter, the route will
only be in effect for calls that originate from a local user. The destination line 'RESTART'
prompts a new pass through the call routing table, whereby the source line is deleted. Due to
the missing source line, the route does not match this call during the second pass.
