Create conference with 2 existing calls

[chrischevy]

I know how to create a conference by calling Person A, press Conference, call Person B and press Conference again.

However, this scenario is not good all the time. Let's say I receive 2 calls, and I need to create a conference, I can't do it...

How can I create a conference by merging 2 existing calls without pressing conference before placing the second call ?

Not sure if I'm clear

I found these instructions but they don't work (there is no "Send" or "Select" button at step 4). I just keep switching between calls

Joining Two Calls in a Conference
You can select a hold call to join into a conference call with the active call.
Procedure
1. Place two or more calls using the same or different accounts on the phone.
2. Select the desired call for conference and ensure that the call is active.
3. Press Conference (Conf).
4. Select a desired hold call, and then press Send.
On the SIP-T48S/T48G IP phone, tap the desired hold call from the left sidebar.
On the SIP-T42S/T42G/T41S/T41P/T40P/T40G IP phone, press Select.
The active call and the selected hold call are joined into a conference. If there are multiple hold calls, the other hold
calls on the same or different accounts remain hold

Hi Dear friend,

This is Evan from Yealink Support Team, nice to know you here!

I tested locally, it worked.
For example:
1. Phone A calls Phones B, and Phone B picks-up this call;
2. Then Phone B holds Phone A, and make a new call C, next, C picks-up this call.
3. The phone A press "Conf" key to conference these calls.
4. Then select this held call A, then press send to create the conference.

Please create a new ticket to us if any other questions. Now, we support in ticket system.

Hello, I was looking into this stuff too.
With our old T20 and T22, you could press "conference" when you already had two active calls (one of them on hold, actually) and they would have merged in a conference.
With T21PE2 and T43U, if you press "conference" when you already have two active calls, it tries to call a third number... is there a way to just merge the existing calls?

Example:
1. Phone A calls Phone B, B picks-up;
2. Then Phone A holds Phone 2 and makes a new call to Phone C, and C pick-ups his call.
3. Phone A presses "conf" key. The phone asks to type a new number to initiate a conference with yet another phone. Makes sense in case you want to make a 4-way conference I guess, but that's quite unlikely. Is there a way to merge the two calls at this point?

Nevermind, I figured it out.

You have to press "Conference", then "down arrow" (to highlight the call on hold) and then "OK".
