How to Upgrade from Cisco SIP SRST 3.0 to Cisco Unified SIP

SRST 4.0

This section contains the following procedures:

• Disabling Call Redirection, page 18 (required)

• Enabling SIP-to-SIP Connection Capabilities, page 21 (required)

Disabling Call Redirection

Because Version 4.0 uses a B2BUA and not a redirect server, call redirection must be disabled if it was

previously enabled. Complete the following tasks as required, depending on whether call redirection was

enabled globally or on a dial-peer basis.

• Disabling Call Redirection Globally, page 18

• Disabling Call Redirection on a Specific VoIP Dial Peer, page 19

Disabling Call Redirection Globally

To disable global IP-to-IP call redirection for all VoIP dial peers, use voice service configuration mode.

Note When IP-to-IP redirection is configured in dial-peer configuration mode, the configuration for the

specific dial peer takes precedence over the global configuration entered under voice service

configuration mode.
