IP PBXs USER MANUAL

To park a call, extension user could dial *4 during a live call, and then listen as the system tells you where you can retrieve the call (usually
extension 41). The second call will be parked on 42, and it continues to park on orderly.
To retrieve the parked calls, user should dial the retrieve number given by the IPPBX system. And this could be done by any extension.
A call could be parked for maximally 120 seconds before it goes back to the extension which parked it. And the parking lot (call retrieve
numbers) could be monitored by BLF. It’s helpful if the operator wants to know if there are calls parked on the IPPBX system.

Call Transfer feature codes
Call Transfer is used to transfer a call in progress to some other destinations. There are two types of call transfer.
Attended call transfer - Where the call is placed on hold, a call is placed to another party, and a conversation can take place
privately before the caller on hold is connected to the new destination. It is also referred to "Supervised Call Transfer".
Blind call transfer - Where the call is transferred to the other destinations without intervention (the other destination could ring out
and may not be answered for instance).
In a live call, you can press # key and the IPPBX system prompts “Transfer”, you then enter the number to transfer to, this call will be
transferred instantly and the user can hang up. If the transferred number doesn’t answer this call then it will go to voicemail.
If blind transfer sometimes seems inappropriate, you may use attended transfer feature. In a live call, you can press *2 and the IPPBX
system prompts “Transfer”, you then enter the number to transfer to, after someone answers your call, you can introduce this call and
hang up at which point the call is transferred.
In an attended transfer, if the third party rang for 15 seconds without answering, the extension user will go back to the caller and the
transfer is terminated. You may also manually abort the transfer by pressing * when the third party is still ringing.

Blacklist feature codes
Black list feature codes allow the extension users to add external phone numbers to IPPBX system blacklist from their phones,
consequently the numbers added will not be able to dial in to the IPPBX system.
Adding blacklist numbers from phone by using feature codes is the same as adding blacklist numbers from admin and operator UI.
Blacklist the last caller allows you to dial *76 to directly add the last caller’s number to the IPPBX blacklist.
You may also dial *75 (end with #) and follow the voice prompts to specify the number you wish to blacklist to add numbers to the IPPBX
system blacklist.
To remove numbers from black list (whitelist a number), you can dial *075 (end with #) and follow the voice prompts to specify the
number you wish to whitelist.
