114 CHAPTER 8: U SING THE VCX USER INTERFACECall Transfer, Call Conferencing, and Bridged Line CallsBridged calls can be transferred by either the primary phone or thesecondary phone. The primary phone user and secondary phone user canalso set up a conference with a bridged call.If the primary phone is on a bridged call and presses the Transfer button,the primary phone user hears a dial tone. The user can then enter atelephone number to start attended or unattended call transfer. Whilethe primary phone user enters the phone number, the calling party is puton hold. However, the light for BSA line on the secondary phone remainson (does not blink as it would for a non-bridged call on hold).While on a bridged call, the primary phone user can also press a free SAline to transfer the call from a BSA line to a SA line. Or, a call connectedon a SA line can be transferred from the SA line to its BSA line. Asecondary phone user, however, can only transfer a call from an SA line toBSA line but cannot transfer a bridged call to an SA line.Both primary and secondary phones can set up a 3-way conference callon a bridged line.Call Park and Bridged Line CallsEither the primary phone user or the secondary phone user can park acall.When either a primary or secondary phone user parks a call and the callpark timeout value is reached (the default is 5 minutes), the parked callrings back only on the phone that parked the call. For example, if aprimary phone user parks a bridged call to a Call Park extension and noone picks up the parked call, after 5 minutes the parked call rings backonly on the primary phone that parked the call. The call does not ringback on a secondary phone or on any other primary login instance. Whenthe primary phone answers the call, the SA status light on primary phonelights but the BSA status lights on the bridged phones do not light.A parked call that rings back on a primary phone rings on the first free SAline.A parked call that rings back on a secondary phone rings on the first freeSA line.
