Configure Overlap Dialing for Call Routing

When you enable overlap dialing and set the incoming match pattern, the Oracle® Enterprise Session Border Controller (Enterprise SBC) can work with the information in the SETUP message to successfully route calls through the Primary Rate Interface (PRI) and Basic Rate Interface (BRI) in a Time Division Multiplexing (TDM ) deployment.

  • Plan the match patterns that you want for incoming calls. See "Incoming Call Patterns Guidelines" for rules and syntax.
  • Confirm that the TDM Profile that you want to enable for overlap dialing exists.

Note:

If the TDM Profile that you want does not exist, you can set the Overlap Dial and Incoming Pattern parameters when you create the profile. The following procedure assumes the profile already exists.

Access TDM Config and use the TDM Profile sub-element to set the OverlapDial and Incoming Pattern parameters.

  1. Access the tdm-profile configuration element. 
    ORACLE# configure terminal
ORACLE(configure)# system
ORACLE(system)# tdm-config
ORACLE(tdm-config)# tdm-profile
  2. Type select to display the existing tdm-profile objects.
    For example: 
    ORACLE(tdm-profile)# select 
<name>:
1: profile 1
2: profile 2
3: profile 3
4: profile 4

selection:1
ORACLE(tdm-profile)#
  3. Select the TDM profile that you want.
  4. Set the Overlap Dial parameter to Incoming.
  5. Set a list of extension numbers or match patterns for the Incoming Pattern parameter.

    Separate single extension numbers with the vertical bar (|) character. A pattern starts with the underscore (_) character. In an extension pattern, note the meaning of the following characters:

    X matches any digit from 0-9

    Z matches any digit from 1-9

    N matches any digit from 2-9

    [1237-9] matches any digit in the brackets (in this example, 1,2,3,7,8,9).

    . wildcard matches one or more characters

    ! wildcard matches zero or more characters immediately

    Syntax examples:
    Suppose the main number is 800-555-1234, one key extension is number 80, and the range of other extensions is from 8100-8399.
    • Match the exact number including the extension: 800555123480
    • Match the extension in a range: _80055512348[1-3]XX
    • Match the exact number including the extension or match an extension in a range: 800555123480|_80055512348[1-3]XX
  6. Type done to save the configuration.
