2.4.2.9 Call Hold

Most PBXs can associate multiple calls with a single line. A call can be placed on hard hold. This frees up the user's line/address to make other calls. The TAPI DLL can place a call on hold by invoking TSPI_lineHold. The TAPI DLL may retrieve an on-hold call by invoking TSPI_lineUnhold.

Hard hold is different from a consultation hold. A call is automatically placed on consultation hold, for example, when a call is prepared for transfer or conference.

TSPI_lineHold

Places the specified call on hard hold.

TSPI_lineUnhold

Retrieves a held call.
