How to switch between multiple phone calls without losing anyone can seem tricky but the PENGUIN Phone System has you covered. 

While you are already on a call you receive another call:

• Press the 'Answer' softkey on your phone
• The phone system will automatically place your current call on hold
• The first caller will hear hold music
• You will be talking to the second caller

To switch back to the first call:

• Toggle down using the down arrow directional pad to highlight the first call (non-touchscreen Polycoms only) -or- touch the first call on your IP Phones screen (on touch screen polycoms only) to highlight it
• Press the 'Resume' softkey
• This will put the second caller on hold automatically and answer the first caller again
• The second caller will hear hold music
• You will be talking to the first caller again

To disconnect a call without losing the other caller:

• Press the 'End Call' softkey on the call you wish to disconnect
• The call you disconnected will end and disappear from the screen
• The other call(s) will remain on hold
• To pick up another call highlight it using the directional key pad (described above) or tap it with your finger (on touch screen polycoms only)
• Press the 'Resume' softkey
• You will now be talking with the caller who was on hold while you disconnected the other call

The most important thing to note here is that the system will automatically place calls on hold for you and will not disconnect a call unless you hang up on that call or press end call. It will also preserve any saved calls and keep them active and on hold no matter what you do with other calls. Only the call you are actively on is affected by the softkey options you choose at that time.
