Setup Advanced Prefix Set
A Prefix Set groups one or more prefixes together. This set can then be applied to a Customer or Route. Without the ability to use a Prefix Set, each individual Customer or Route would need to be configured manually each time, opening up the possibility of human error. With Prefix Sets, we avoid these errors and reduce configuration time overall. ConnexCS supports plain text as well as regular expressions when building Prefix Sets for greater flexibility.
Configure Prefix Set¶
Step 1: Create Prefix Set
- Click the .
- Name the set.
- Data includes the prefixes, one per line (plain-text or regular expressions). See Example Dial Strings for Prefix sets below.
- Flags (optional) is used to setup global blacklists. See Flags below.
Step 2: Apply Prefix Set Prefix Sets can be applied to the following locations under the Management menu:
Customer Routing Ingress Routing Basic Dial String Prefix Set
Routing Routing Global Basic Dial String Prefix Set
Rate Card Customer Rate Cards Profits Config Prefix Set
Use Flags to create a Global CLI Blacklist or a Global Dialled Number Blacklist (Aka Block List). This will prevent all calls going through the system which match the defined prefix set.
Blacklist or Do Not Call list
Flags are used for large amounts of numbers that change infrequently. If you are looking to manage a DNC list, please review our Do Not Call (DNC) setup.
Example Dial Strings for Prefix sets¶
Prefix Sets, as well as all Dial String fields, accept plain text or regular expressions. List only one prefix per line. Here are 3 samples, using plain-text, regex, or a mix:
Regular Expression (RegEx)
Combination (UK Landline & Canada)
