Configuring Dial Access String (DAS) Rules

The DAS Rules options are available in the MCA navigation pane only when you set Enable

DAS Rules on the Systems Option page.

Consider the following when you configure the dialing plan:

• Check for special or specific dialing plans for your company. For example, if you have

access codes to connect to branch offices, remote locations, or international offices.

• Check for blocked area codes (such as 800 or 900) and if so, what numbers that are blocked.

• Check that all call processing programming has been completed, including Automatic Route

Selection (ARS), dial rules, and other related information.

MCA uses DAS rules to dial outside numbers and internal private branch exchange (PBX)

extensions. You can configure the MCA server with rules to handle a wide range of call routing

and dial plan requirements. These rules can handle international dialing, PBX extension calling,

and sophisticated SIP call processing.

DAS rules are a set of up to 20 UNIX

regular expressions that are applied to dialed digits. The

rules are applied in the order in which they are listed in the DAS Rules table. The output of

each rule is the input to the next rule. The result is used as the dialed digits that are processed

through conferencing server call processing.

To configure dialing rule parameters:

1. From the MCA administrator page, click DAS Rules from the navigation pane.

Note: When DAS rules are applied, Outgoing Prefix and Max Extension Length are

not applicable (see Configuring System Options on page 36).

Note: DAS rules are processed by the Perl Compatible Regular Expressions (PCRE)

library distributed as libpcre. Details on the library are available from

http://www.pcre.org/. MCA supports only the 'g' flag.

Note: Performing the following procedure disconnects all active calls.
