Hookflash Detect  

Hookflash is either a button on the phone to simulate the quick offhook/onhook/offhook cycle or the actual cycle itself. Hookflash can be used as the trigger event for switching to call waiting or three way call conferencing.

On Hook Signaling

On-hook signaling indicates the phone can accept any features or signals that only enabled while the phone is on-hook.

Call Wait

Call waiting: When an incoming call is received the receiver of the call is notified by a tone of an incoming call; the hookflash trigger switches the subscriber between the ongoing call and the incoming call. The original call is placed on hold.

Call Transfer

When the call transfer feature is added to hookflash, the system supports transferring calls. The hookflash trigger during an ongoing call gives the subscriber a secondary dialtone and will accept dialing. The original call is on hold until another hookflash.

Conference

Local call conferencing feature is supported only with SIP.

MGCP and H.248 have the conferencing feature on their switch side.

call conferencing feature enables three-way conference calls during which three parties can use one calling session to communicate. Three-way call conferencing follows the Telcordia (Bellcore) three-way calling standard called Telcordia - TR - TSY - 000577, Three-Way Calling.
