You can set up the HorstBox to use a certain telephone service
provider for every out-bound call, differentiate even for calls to
mobile phone numbers or overseacalls.
Define a new call rule and activate the option with amended
phone number.
Example
Always use another account for certain out-bound calls:
1. Define a new dial rule.
2. Enter the first digits, e.g. the area code, in the field PREFIXES
(1 in fig. 4.17)
3. Choose the option always or define the time period for the
rule to be applied.
4. Choose the option connect and the account to use, e.g. "‘VoIP
account 1"’.
5. Leave the fields PREFIXES (2 in fig. 4.17) and MODIFIER (3
in fig. 4.17) blank.
6. To save the new rule, click on SAVE.
All out-bound calls starting with the saved digits will be routed
via the chosen account.
