SUMMARY STEPS

1. call-manager-fallback

2. transfer-pattern transfer-pattern

3. exit

DETAILED STEPS

Example

In the following example, the transfer-pattern command permits transfers from a non-IP phone number

to any Cisco Unified IP Phone on the same IP network with a number in the range from 5550100 to

5550199:

call-manager-fallback

transfer-pattern 55501..

Enabling Consultative Call Transfer and Forward Using H.450.2 and H.450.3 with Cisco SRST 3.0

Consultative call transfer using H.450.2 adds support for initiating call transfers and call forwarding on

a call leg using the ITU-T H.450.2 and ITU-T H.450.3 standards. Call transfers and call forwarding using

H.450.2 and H.450.3 can be blind or consultative. A blind call transfer or blind call forward is one in

which the transferring or forwarding phone connects the caller to a destination line before a ringing tone

begins. A consultative transfer is one in which the transferring or forwarding party either connects the

caller to a ringing phone (ringback heard) or speaks with the third party before connecting the caller to

the third party.

Note For Cisco SRST 3.1 and later and Cisco Unified SRST 4.0 and later, call transfer and call forward using

H.450.2 is supported automatically with the default session application.
