pattern
Example:
Router(config-cm-fallback)# call-forward

Specifies the H.450.3 standard for call forwarding.
•
pattern
: Digits to match for call forwarding using the
H.450.3 standard. If an incoming calling-party number
matches the pattern, it can be forwarded using the
H.450.3 standard. A pattern of .T forwards all calling

Step 3
transfer-system
{
blind
|
full-blind
|
full-consult
|
local-consult
}
Example:
Router(config-cm-fallback)# transfer-system
full-consult
Not supported if the transfer-to destination is on the Cisco
ATA, Cisco VG224, or an SCCP-controlled FXS port.
Defines the call-transfer method for all lines served by the
Cisco Unified SRST router.
•
blind
: Calls are transferred without consultation with a
single phone line using the Cisco proprietary method.
Note
We do not recommend the
blind
keyword. Use
either the
full-blind
or
full-consult
keyword
instead.
•
full-blind
: Calls are transferred without consultation
using H.450.2 standard methods.
•
full-consult
: Calls are transferred with consultation
using a second phone line if available. The calls fall
back to
full-blind
if the second line is unavailable.
•
local-consult
: Calls are transferred with local
consultation using a second phone line if available. The
calls fall back to
blind
for nonlocal consultation or
nonlocal transfer target.
Step 4
transfer-pattern
transfer-pattern
Example:
Router(config-cm-fallback)# transfer-pattern
52540..
Allows transfer of telephone calls by Cisco Unified IP
Phones to specified phone number patterns.
•
transfer-pattern
: String of digits for permitted call
transfers. Wildcards are allowed.
Step 5
exit
Example:
Router(config-cm-fallback)# exit
Exits call-manager-fallback configuration mode.
Timesaver
Before exiting call-manager-fallback
configuration mode, configure any other
parameters that you need to set for the entire
Cisco Unified SRST phone network.
