5. How do I do call waiting/call hold/call retrieve?

- Put your current call on hold and answer the incoming call - after hearing the call waiting tone, press and immediately release the Flash button on your telephone.
- Put your current call on hold and switch to another call - press and immediately release the Flash button on your telephone.
- Hang up your current call before answering the incoming call - hang up the phone and wait for answering the incoming call.
- Hang up the current active call and switch back to the other call - hang up and wait for the phone to ring. Then pick up the phone to return to the other call.

6. Why doesn't call waiting work as expected?

An incoming caller will receive a busy signal if:

- You have two calls active (one active and one on hold; or both active by using Three-Way Calling).
- You are dialing a number on the B channel the incoming caller is attempting to reach, but have not yet established a connection.

If no action is taken to answer the call (call waiting indicator tone is ignored), the call waiting tones will disappear after about 20 seconds.

7. How do I do three way calling?

- Press the Flash key to put the existing call on hold and receive a dial tone.
- Dial the third party's phone number.
- When you are ready to conference the call together, press the Flash key again to establish a three way conference call.

8. How do I remove a party from the three-way calling?

Simply press the Flash key. The last call that was added to the conference is dropped.

If you hang up your telephone during a three-way call and the two other callers remain on the line, the ISDN network will do an implicit transfer to directly connect the two remaining callers together.

9. How do I do call transfer?

Call Transfer allows you to transfer an active call to a third party. This service must be subscribed from your telephone company.

Transferring an active call to a third party:

- Once you have an active call (Caller A), press Flash key to put Caller A on hold and receive a dial tone.
- Dial the third party's phone number (Caller B).
- When you are ready to conference the two calls together, press Flash key to a Three-Way Conference call.
- Hang up the phone. The ISDN network does an implicit transfer to directly connect Caller A with Caller B.

10. How do I blind call transfer?

- Once you have an active call (Caller A), press Flash key to put the existing call on hold and receive a dial tone.
- Dial the third party's phone number (Caller B).
- Before Caller B picks up the call, you can transfer the call by pressing the Flash key. The call is automatically transferred.

11. What is call forwarding and how do I do it?

The call forwarding means the switch will ring another number at a place where you will be when sometime dials your directory number. There are two methods to active call forwarding, either method should work fine and you can use whichever one you are most comfortable.

- The first is exactly the same as on an analog line, i.e., you pick up the handset and dial the access code assign by your telephone company and the number that you want the calls forwarded. Check with your telephone company for this access code.
- The second is with the 'phone flash' commands where you pick up the handset and press the flash key before dialing the following:

Command | Meaning
*20*forward-number# | Active CFB (Call Forwarding Busy)
*21*forward-number# | Active CFU (Call Forwarding Unconditional)
*22*forward-number# | Active CFNR (Call Forwarding No Reply
#20# | Deactive CFB
#21# | Deactive CFU
#22# | Deactive CFNR

12. How do I suspend/resume a phone call (terminal portability)?

The Terminal Portability service allows you to suspend a phone call temporarily. You can then resume this call later, at another location if you so wish.

To suspend an active phone call:

- Press the flash key twice.
- Dial *3n*#, where n is any number from 1 to 9.

To resume your phone call:

- Reconnect at a (n) (ISDN) telephone that is linked to the same S/T interface (Network Terminator-1, NT1) where you suspended the call.
- Pick up the handset and press the Flash key
- Dial #3n#, where n is any number from 1 to 9, but should be identical to that used above.

13. What is reminder ring?

The Prestige sends a single short ring to your telephone every time a call has been forwarded(US switches only).

14. Why doesn't my answering machine on POTS port stop recording?

Most answering machines stop recording when a busy tone is detected. But some may not. Some answering machine only recongnize that a calling party has hung up after a period of silence. In this case, if such an answering machine is attched to the POTS port of Prestige you need to configure the 'Hangup Silence Time(sec)=' in SMT menu 2.1 to determine the silence time period. By doing so, once Prestige receives busy tones from the switch it sends the silence tone to the answering machine on POTS meanwhile.

15. What are CLIP and CLIR in Advanced Setup of Menu 2 (European firmware)?

CLIP or CLIR refers to CLID Presented or Restricted. The Prestige can set the CLIP/CLIR bit at SETUP message to request the Switch, to include the calling party number or not when the switch sends the SETUP message to the called party. You need subscribe to it first (see supplemental services)

16. Does Prestige support MP callback to dial-in users?

No, Prestige only supports single link PPP to dial-in users.
