Cisco Cisco Unified Customer Voice Portal 10.5(1)

For example, to use the AT&T Transfer Connect feature to transfer the call to the number
“4441234”, configure the label as 

.

• Usually the PSTN switch expects a delay between the *8 and the phone number. Each comma

represents 100ms by default. It can be changed with the SetTakebackDelay command in
VBAdmin.

• In outpulse transfer mode, Unified CVP will send whatever digits are in the label to the

Gateway for outpulsing. It is the customer’s responsibility to confirm interoperability with
the target switch.

• In your Unified ICME script when using outpulse transfers with SIP calls, digits can only be

outpulsed on a call that has already been established. This means that it is necessary to transfer
the call to the VXML gateway with a run external script node before you can send the DTMF*8
label. The Unified ICME script cannot send the DTMF*8 label back to Unified CVP for the
first connect message in the call because the call has not been answered at this point. The
Unified CVP Call Server uses SIP INFO messages to send the digits to the gateway for
outpulsing.

• When using outpulse transfers with SIP, you can also use the comma duration as the default

interdigit pause duration. For example, with the default 100 msec comma duration, a label
such as "DTMF*8,,,8009785001" will have 300 msecs between the first 8 and the second 8.
The interdigit pause will also be 100 msecs. The tone duration is also configurable and defaults
to 100 msecs.

Defining a Unified ICME Script Label for Two B-Channel Transfer (TBCT)

For Unified CVP calls that require Two B-Channel Transfer (TBCT) mode, add a label node
to your Unified ICME script with the following syntax:

Replace 8005551212 with your transfer destination target; 

 and the

sign are

mandatory.

By configuring the target label in this form, Unified CVP sends the digits to the Ingress endpoint
for Two B-Channel transfer.

Defining a Unified ICME Script Label for Hookflash Transfer

Labels in Unified ICME scripts for Unified CVP calls that require hookflash transfer mode must
be prepended with the characters 

. By configuring the target label with the form 

(where 

 are the digits to call) Unified CVP sends the digits to the Ingress endpoint for

hookflash transfer.

If the switch requires a pause after the hookflash, insert commas between the 

 and the transfer

number. (Each comma represents 100 milliseconds.)
