User Experience Features

Attended Transfer

When you transfer a call to another extension and speak to the other extension before putting the call through.

On a Yealink desktop phone; *Press transfer, extension number, ok

On a Gigaset cordless phone; *3, extension number, #

While on conversation with another party, you dial the attended transfer key sequence. MyPBX says "Transfer" then gives you a dial tone, while putting the other party on hold. You dial the transferee number and talk with the transferee to introduce the call, then you can hang up and the other party will be connected with the transferee. In case the transferee does not want to answer the call, he/she simply hangs up and you will be back to your original conversation.

You can professionally put a customer on hold while checking with your director first if he wants to take the call instead of just putting it through to his office. Your director may want to avoid certain calls at certain times and this gives you the opportunity to check whether your director wants to take the call or not.

Number Blacklist is used to block an incoming call you do not want to answer.

Programming required

Blacklist is used to block an incoming/outgoing call. If the incoming call number is registered in the number blacklist, the caller will hear the following: “The number you have dialed is not in service. Please check the number and try again”. The system will then disconnect the call.

If you are receiving unwanted automated sales calls, nuisance or prank calls or just want to avoid someone. Please note CLI must be activated on all incoming lines for Blacklist to operate successfully.

Blind Transfer

When you transfer a call to another extension without speaking to the other extension first, the transfer is therefore ‘blind’.

Call Pickup

Call pick-up if activated is used to pick up another users call if their phone is ringing and they are unable to answer it.

Under such an arrangement, using “call pick-up” will only pick up a call in the same group. There are two main types:-Group call pickup, this allows you to collect a call from any ringing phone that is in the same pickup group as you, if there were more than one phone ringing then you would have no control over which call you collected. Directed pickup, this allows you to pickup a call at a specific extension, maybe you're in another office and you hear a phone ringing and wonder if it's yours. You dial the pickup number and your extension, and the call will only transfer if it is your extension. The code would differ for directed pickup: *04 Ext number, ok

The phone is taken off-hook or sends a signal to the PBX stating it is busy, and not available for calls. The call is then handled by the method programmed in the busy event, such as forwarding to another free extension or to voice mail. MyPBX implemented in BUSY mode, the call will be forwarded to extensions’ voicemail.

You may be out to lunch or working on an important task and do not want to be disturbed, rather activate DND and let the caller go to voicemail or reception.

FAX (T.38)

The PBX supports Fax Routing.

Programming Required

The PBX can be set up to detect faxes (Fax Tones) and automatically route the faxes to a desired destination either E-mail or an Extension. Customize an E-mail address to receive the faxes. You should first configure the “Voicemail Settings->SMTP Settings for Voicemail” correctly before you use this option. Send faxes to an extension. If choosing a FXS extension here, the fax will be sent to the FXS port selected, you should connect a fax machine to this FXS port. If Choosing a VoIP extension, the fax will be sent to the extension’s voicemail as an attachment.

If you seldom receive faxes on your fixed Telkom line you may want to use the spare capacity for voice calls and plug this line into your PBX. If someone sends a FAX to you via this line it will be detected and sent via e-mail or straight to an analogue FXS extension (Old Fax Machine)

QoS (Quality of Service)

QoS (Quality of Service) is a major issue in VOIP implementations. The issue is how to guarantee that packet traffic for a voice or media connection will not be delayed or dropped due to interference from other lower priority traffic such as browsing.


When the network capacity is insufficient, QoS provides priority to users by setting the value. Voice will get priority over other traffic.

Using devices that allow for QoS will result in clear voice transmission.

DID (Direct Inward Dialing)

Also called DDI (Direct Dial-In). This is used on ISDN, PRI or SIP trunks. There is a range of numbers allocated to the line and all calls to these numbers are forwarded to the same line trunk by the telecoms network. DID feature on the IP PBX will identify which number in the range has been dialed and the PBX can then route the incoming call in any way you would like.

Programming required.

As calls are presented to the PBX, the dialed destination number (DNIS) is transmitted, usually partially (e.g., last four digits), so that the PBX can route the call directly to the desired telephone extension within the organization without the need for an operator or attendant. The service allows direct inward call routing to each extension while maintaining only a limited number of subscriber lines to satisfy the average concurrent usage of the customer.

ISDN has typically been used in the past on analogue PBX systems because of the wider number range available on these trunks and the direct dial in capabilities. Nowadays multiple SIP (VoIP) numbers can be used to achieve the same effect at a lower cost. You can also set up an IVR and direct dial an extension through an IVR so the new technology has eliminated the necessity of using ISDN.

Forwarding voicemails is as easy as forwarding an e-mail. Create an e-mail distribution list to send voicemail to multiple parties via e-mail.
