Overview of Cisco IOS SRST This chapter describes Cisco Survivable Remote Site Telephony (SRST) and what it does. It also includes information about Cisco IP phone, platform, and Cisco CallManager version support; specifications; features; restrictions; and where to find additional reference documents.
Overview of Cisco IOS SRST Cisco SRST Description providing call-handling support for Cisco IP phones directly from the Cisco SRST router. The system automatically detects a failure and uses Simple Network Auto Provisioning (SNAP) technology to autoconfigure the branch office router to provide call processing for Cisco IP phones that are registered with the router. When the WAN link or connection to the primary Cisco CallManager is restored, call handling reverts back to the primary Cisco CallManager.
Overview of Cisco IOS SRST Cisco SRST Description Once a connection is reestablished with Cisco CallManager, Cisco IP phones automatically cancel their registration with the Cisco SRST router. However, if a WAN link is unstable, Cisco IP phones can bounce between Cisco CallManager and Cisco SRST. A Cisco IP phone cannot reestablish a connection with the primary Cisco CallManager at the central office if it is currently engaged in an active call.

Example: Router(config)# call-manager-fallback Step 2 call-forward busy directory-number Configures call forwarding to another number when the Cisco IP phone is busy. • Example: Router(config-cm-fallback)# call-forward busy 50..
Setting Up Call Handling How to Set Up Call Handling Configuring Call Rerouting Note The alias command obsoletes the default-destination command and is recommended over the default-destination command. The alias command provides a mechanism for rerouting calls to telephone numbers that are unavailable during fallback. Up to 50 sets of rerouting alias rules can be created for calls to telephone numbers that are unavailable during Cisco CallManager fallback.
Setting Up Call Handling How to Set Up Call Handling In this example, you have created a second dial peer for 1001 to route calls to 1001, but that has preference 1 and call forwarding to 2001. Because the preference on the dial peer created by the alias command is now a lower numeric value than the preference that the dial peer first created, all calls come initially to the dial peer created by the alias command.
Setting Up Call Handling How to Set Up Call Handling DETAILED STEPS Step 1 Command or Action Purpose call-manager-fallback Enters call-manager-fallback configuration mode. Example: Router(config)# call-manager-fallback Step 2 alias tag number-pattern to alternate-number [preference preference-value] [cfw number timeout timeout-value] [huntstop] Example: Router(config-cm-fallback)# alias 1 60..

Example: Router(config)# call-manager-fallback Step 2 Disables huntstop. no huntstop Example: Router(config-cm-fallback)# no huntstop Step 3 alias tag number-pattern to alternate-number Example: Creates a set rules for rerouting calls to sets of phones that are unavailable during Cisco CallManager fallback.
Setting Up Call Handling How to Set Up Call Handling When a DID incoming call to 800 555-0100 is received, the alias command routes the call at random to one of the four extensions (5001 to 5004). Because the pickup command is configured, if the DID call rings on extension 5002, the call can be answered from any of the other extensions (5001, 5003, 5004) by pressing the PickUp soft key. The pickup command works by finding a match based on the incoming DID called number.
Setting Up Call Handling How to Set Up Call Handling DETAILED STEPS Step 1 Command or Action Purpose call-manager-fallback Enters call-manager-fallback configuration mode. Example: Router(config)# call-manager-fallback Step 2 dialplan-pattern tag pattern extension-length length [extension-pattern extension-pattern] [no-reg] Example: Router(config-cm-fallback)# dialplan-pattern 1 4085550100 extension-length 3 extension-pattern 4..
Setting Up Call Handling How to Set Up Call Handling In the following example, the leading prefix digit for the 3-digit extension numbers is transformed from 0 to 4, so that the extension-number range becomes 400 to 499. call-manager-fallback dialplan-pattern 1 40855500.. extension-length 3 extension-pattern 4.. In the following example, the dialplan-pattern command creates dial-plan pattern 2 for extensions 801 to 899 with the telephone prefix starting with 4085559.

Setting Up Call Handling How to Set Up Call Handling In the configuration below, the voice translation-rule and the rule command allow you to set and define how a number is to be manipulated. The translate command in voice translation-profile mode defines the type of number you are going to manipulate; such as a called, calling, or a redirecting number. Once you have defined your translation profiles, you can then apply the translation profiles in various places, such as dial peers and voice ports.
Setting Up Call Handling How to Set Up Call Handling DETAILED STEPS Step 1 Command or Action Purpose voice translation-rule number Defines a translation rule for voice calls and enters voice translation-rule configuration mode. Example: • Router(config)# voice translation-rule 1 Step 2 rule precedence/match-pattern/ /replace-pattern/ Example: Router(cfg-translation-rule)# rule 1/^9/ // Step 3 number—Number that identifies the translation rule. Range is from 1 to 2147483647.

Setting Up Secure SRST This chapter describes new SRST security features such as authentication, integrity, and media encryption.
Setting Up Secure SRST Restrictions for Setting Up Secure SRST Public Key Infrastructure • Set the clock, either manually or by using Network Time Protocol (NTP). Setting the clock ensures synchronicity with Cisco CallManager. • Enable the IP HTTP server (Cisco IOS processor) with the ip http server command, if not already enabled. For more information on public key infrastructure (PKI) deployment, see the Cisco IOS Certificate Server feature.
Setting Up Secure SRST Information About Setting Up Secure SRST • When a Secure Real-Time Transport Protocol (SRTP) encrypted call is made between Cisco IP phone endpoints or from a Cisco IP phone to a gateway endpoint, a lock icon is displayed on the IP phones. The lock indicates security only for the IP leg of the call. Security of the PSTN leg is not implied. • Secure SRST is supported only within the scope of a single router.
Setting Up Secure SRST Information About Setting Up Secure SRST Secure SRST provides new SRST security features such as authentication, integrity, and media encryption. Authentication provides assurance to one party that another party is whom it claims to be. Integrity provides assurance that the given data has not been altered between the entities. Encryption implies confidentiality; that is, that no one can read the data except the intended recipient.
Setting Up Secure SRST Information About Setting Up Secure SRST SRST Routers and PKI The transfer of certificates between an SRST router and Cisco CallManager is mandatory for secure SRST functionality. Public key infrastructure (PKI) commands are used to generate, import, and export the certificates for secure SRST. Table 7 shows the secure SRST supported Cisco IP phones and the appropriate certificate for each phone.

Appendix A: Preparing Cisco SRST Support for SIP Cisco Survivable Remote Site Telephony (SRST) supports incoming and outgoing Session Initiation Protocol (SIP) calls to and from IP phones and router voice gateway voice ports, but does not support direct attachment of SIP phones to Cisco SRST. SIP may be used in situations where the SRST router is separate from the PSTN gateway and the SRST and PSTN gateways are linked together using SIP (instead of H.323).
Appendix A: Preparing Cisco SRST Support for SIP DTMF Relay for SIP Applications and Voice Mail The SIP DTMF relay method is needed in the following situations: Note • When SIP is used to connect a Cisco SRST system to a remote SIP-based IVR or voice-mail application, such as Cisco Unity. • When SIP is used to connect a Cisco SRST system to a remote SIP-PSTN voice gateway that goes through the PSTN to a voice-mail or IVR application.
