How to Configure Cisco Unified SCCP SRST Configuring Call Handling DETAILED STEPS Step 1 Command or Action call-manager-fallback Purpose Enters call-manager-fallback configuration mode. Step 2 Step 3 Example: Router(config)# call-manager-fallback dialplan-pattern tag pattern extension-length length [extension-pattern extension-pattern] [no-reg] Creates a global prefix that can be used to expand the abbreviated extension numbers into fully qualified E.164 numbers Example: Router(config-cm-fallback)# dialplan-pattern 1 4085550100 extension-length 3 extension-pattern 4.. Note This example maps all extension numbers 4xx to the PSTN number 40855501xx, so that extension 412 corresponds to 4085550112. • tag: Dial-plan string tag used before a 10-digit telephone number. The tag number is from 1 to 5. • pattern: Dial-plan pattern, such as the area code, the prefix, and the first one or two digits of the extension number, plus wildcard markers or dots (.) for the remainder of the extension number digits. • extension-length: Sets the number of extension digits. • length: The number of extension digits. The range is from 1 to 32. • extension-pattern: (Optional) Sets an extension number's leading digit pattern when it is different from the E.164 telephone number's leading digits defined in the pattern argument. • extension-pattern: (Optional) The extension number's leading digit pattern. Consists of one or more digits and wildcard markers or dots (.). For example, 5.. would include extension 500 to 599; 5... would include 5000 to 5999. • no-reg: (Optional) Prevents the E.164 numbers in the dial peer from registering with the gatekeeper. exit Exits call-manager-fallback configuration mode. Example: Router(config-cm-fallback)# exit Examples The following example shows how to create dial-plan pattern 1 for extension numbers 101 to 199 with the telephone prefix starting with 4085550. If the following example is set, the router will recognize that 4085550144 matches dial-plan pattern 1. It will use the extension-length keyword to extract the last three digits of the number 144 and present this as the caller ID for the incoming call. call-manager-fallback dialplan-pattern 1 40855501.. extension-length 3 no-reg   138 Cisco Unified SCCP and SIP SRST System Administrator Guide OL-13143-04
