Hi this is a great feature on the
Samsung Prostar, I actually find the screen prompts easier to follow than the
pre-programmed button. Whilst on a call the display will read ' CONF PAGE MUTE' press the 1st small button under
CONF. then dial the number, externally or internally, that you want to bring into the conference. then press
CONF again twice, this links the members together, you will see that the
CONF is now under the 3rd
softkey. up to 5 people can be on a call at one time if you have enough channels (lines) available. I have uploaded a video which will help explain this better or visit
www.abbeytelecom.com , I hope that this is of some help.
