Merge conference 3 fusion

Hello,
I'm new to this forum and I do not know if I'm in the right place, pardon the administrator.:crying:

I just posted here because I meet a problem with my note, I am on the forum Galaxy Note, but no one knows answer to my problem:

Whenever I want to do a conference in three merger and I have a message notes "conference has three possible" and on the website of my operator the option is enabled and says I can do up to 5 conferences

Before I was in this market LRT and then I did the wipes cache and dalvik wipe because the phone was very long, it is stopped to work out.

Then I spent a LT6, return LT1 and LRT now LT9 but it does not work.
Living abroad, this function is very useful to me, I read on different forum fr, us that this problem many people encounter and need to flash fixed the bug .... ?

If anyone can help me find a solution that would be great!

I wish you all a good weekend. :cowboy::cool:
