is it possible that some how if we can make such software which can be placed here on this website for 8 lines intercom system so that other people will not have much trouble in understanding the software...


Stating your request as above can only be interpreted as anothe attempt by you to make us do it for you. Trying to appear altruistic does not cut it.

If you have followed the discussions here the theme is:
We will help anyone design/develop soft- and hardware, but we will not give finished designs to those that are too lazzy to do it themselves.

do your own job or find another profession
