Question for anyone who might know. I have tried 3 way conference calling a couple of times on different phones in the house. If I am talking to someone and use the HOOK SWITCH I get the 2nd dialtone. I can call the 2nd number and hit the HOOK SWITCH again and conference all 3 of us. Works good. HOWEVER; if I use the FLASH button like on most cordless type phones without a hookswitch, then I get the 2nd dialtone; I can call the 2nd number and connect. BUT, when I hit the flash button again, it takes me back to the 1st caller and doesn't 3 way the call. If I hit flash again, I can go back to the 2nd caller, but NOT a conference with the 1st caller. Basically, the flash just switches between the 1st and 2nd caller. Any idea on conference calling? Thx..... Mike......
