| Thanks to ALL. I've just undestood what I was looking for is what an option 11c does not support. Therefore I have swallowed my attepmt and sent back to the stomach. Why I wanted to do so was, I saw some Switches like ALCATEL-S12 can do this. You just dial digits from one set, then hung up, in 2 secconds both SETS will ring. This is they you call the other SET. By the way THANKS YOU VERY MUCH. Hassan |
