Conference Calls
 

I have searched for this answer. Maybe someone can tell me this.

How do you conference in the call that is coming in/ call waiting/on hold??? Please help me with this. I have hung up on too many clients b/c I can't figure it out.

Straight from the 700wx guide.

Making a Second Call
You can make a second call while your first call is still
active.
1. Press Hold (left softkey) to put the first call
on hold.
2. To dial a second number, use any of the methods
described in “Making Calls” on page 61. (If you’re
dialing by contact name or with the keyboard,
you must first use the 5-way to select the Dial
Lookup field.)
When two calls are active, your Today screen includes two call status sections,
each representing one of the calls.

Answering a Second Call (Call Waiting)
When you’re on a call and you receive a second call, the call-waiting notification
appears. You can do any of the following:
 Place the current call on hold and answer the new call: Press Answer (left
softkey) or Phone/Talk .
 Send the new caller a text message: Press Menu (right softkey) and select
Ignore with text message.
 Hang up the first call: Press Power/End . (The second call becomes an
incoming call alert, which you can choose to answer or ignore.)
 Send the new call to voicemail: Press Menu (right softkey) and select
Ignore.

Making a Conference Call
When the second call is outgoing, you can join two calls in a conference session.
Additional charges may apply and minutes in your account may be deducted for
each active call. Please contact Sprint for more information.
1. Put the first call on hold, and then place a second
call.
2. Press Conference (left softkey); this joins
the two active calls in a conference.
3. When you’re done, press End Conference
(left softkey); this ends the second call and
returns you to the first call. (If you’re ready to
hang up both calls, press Power/End instead.)

Coz

When I am on a call, and answer a second call....Then flash back to the first call, the second call may hang up, but the line never clears. That is just something that need to be fixed!!!

Yep. I think the Treo can only conference when outgoing.
