How to Configure Cisco Unified SIP SRST Configuring Call Handling Step 6 Command or Action call-forward b2bua mailbox directory-number Example: Router(config-register-pool)# call-forward b2bua mailbox 5007 Step 7 call-forward b2bua noan directory-number timeout seconds Example: Router(config-register-pool)# call-forward b2bua noan 5010 timeout 10 Step 8 end Example: Router(config-register-pool)# end Purpose Controls the specific voice-mail box selected in a voice-mail system at the end of a call forwarding exchange. • directory-number: Telephone number to which calls are forwarded when the forwarded destination is busy or does not answer. Represents a fully qualified E.164 number.  Maximum length of the telephone number is 32. Enables call forwarding for a SIP B2BUA so that incoming calls to an extension that does not answer after a configured amount of time are forwarded to another extension. This command is used if a phone is registered with a Cisco Unified SIP SRST router, but the phone is not reachable because there is no IP connectivity (there is no response to Invite requests). • directory-number: Telephone number to which calls are forwarded. Represents a fully qualified E.164 number. Maximum length of the telephone number is 32. • timeout seconds: Duration, in seconds, that a call can ring with no answer before the call is forwarded to another extension. Range is 3 to 60000.  The default value is 20. Returns to privileged EXEC mode. Configuring Call Blocking Based on Time of Day, Day of Week, or Date This section applies to both SCCP and SIP SRST. Call blocking prevents the unauthorized use of phones and is implemented by matching a pattern of up to 32 digits during a specified time of day, day of week, or date. Cisco Unified SIP SRST provides SIP endpoints the same time-based call blocking mechanism that is currently provided for SCCP phones. The call blocking feature supports all incoming calls, including incoming SIP and analog FXS calls. Note Pin-based exemptions and the "Login" toll-bar override are not supported in Cisco Unified SIP SRST. The commands used for SIP phone call blocking are the same commands that are used for SCCP phones on your Cisco Unified SRST system. The Cisco SRST session application accesses the current after-hours configuration under call-manager-fallback mode and applies it to calls originated by Cisco SIP phones that are registered to the Cisco SRST router. The commands used in call-manager-fallback mode that set block criteria (time/date/block pattern) are the following: • after-hours block pattern pattern-tag pattern [7-24] • after-hours day day start-time stop-time • after-hours date month date start-time stop-time 168 Cisco Unified SCCP and SIP SRST System Administrator Guide OL-13143-04
