The three way conferencing feature allows you to add another party to an existing call, and gives 

you additional flexibility in selecting which call to drop at closure. 

You first need to subscribe this service from your telephone company. Then, issue the command 

[ATS120.7=1&W0Z0] that will assign the Flash key to supplementary service. 

In addition, and for USA only, request the IOC (ISDN Ordering Code) from your telephone 

company. The IOC is used by your omni.net TA as feature access code to conference calls (The 

IOC should range between 0 and 63.) Save the IOC to the omni.net TA by typing the following 

command: 

AT&ZF1=IOC-of-CONFERENCE

 

If you wish to call another party C and let them join in to conference with an existing call, follow 

these steps: 

Step 1.  Press the flash key and immediately release to put the existing caller B on hold and 

receive a dial tone. 

Step 2.  Dial to third party C that you want to invite in your conversation. 

Step 3.  After party C answers, press the flash key and immediately release to establish a 

three way conference call. 

 

 

NOTE: If you wish to cancel your attempt to establish a conference 
call (third party line is busy or if they do not answer), simply hang-up 
the phone and pick it back up after it starts ringing to return to the first 
caller.
