ISDN and Analog Telephone Devices 4-9
To retrieve the call placed on hold, perform the short on-hook or press the Flash key again.
If you have a call on hold and you hang up, the telephone rings, indicating a call is on hold.
Picking up the telephone receiver connects you to the caller on hold.
Call Transfer
Call transfer is the ability to transfer an active call to another number. (Some countries that
use the NET3 switch do not support ISDN provisioning for call transfer.)
Take the following steps to transfer an active incoming call to another telephone number:
Step 1 Perform a short on-hook (quickly press the telephone receiver button once) to
get a dial tone.
If your analog telephone device offers the option, you can press the Flash key
instead of the short on-hook to put the call on hold.
You can also return to the original call by performing another short on-hook.
Step 2 Dial the number to which the call is to be transferred.
Step 3 Hang up the receiver. The call is transferred.
If the transfer fails, the caller remains on hold, and the telephone rings to alert
you to the call on hold.
Three-Way Call Conferencing
Three-way call conferencing adds another party to an active call. (Some countries that use
the NET3 switch do not support ISDN provisioning for three-way call conferencing.) Up
to three people can be connected using three-way conferencing. (It is a known limitation
that no more than two Cisco 700 series routers can be connected.)
Take the following steps to add a third party to an active call:
Step 1 Perform a short on-hook (quickly press the telephone receiver button once) to
get a dial tone.
If your analog telephone device offers the option, you can press the Flash key
instead of the short on-hook to put the call on hold.
