MeritPhone number that subscribes to this service after hearing a second dial tone, and then they can reach that MeritPhone user.

Examples: A Mexico MeritPhone user 6667777 is subscribed to this service, and its Los Angeles access code is 1-213-000-0000. People only just need to dial 1-213-000-0000, then dial 6667777 then press “#” key to reach that MeritPhone user in Mexico.

6.5 Conferencing

How it Works

Once the conferencing call feature has been set-up on your account, you can initiate a conference and have a conference with different parties simultaneously. You will act as a ‘Host’ and invite ‘Participants’ into the conference that you initiated.

Setting yourself up for conference calling now

Go to “My Account” interface

Enter your IP Phone Number, Password and the digits displayed then click Submit.

Click “My Conference Call” in the grey menu bar to view the Conference Call Setup:

Enter the maximum number of people you will likely be conferencing with at one time.

In some circumstances a password will be required for the Host and Participant to be involved in the conference.

Click on the check boxes to select the defaults of 1234 and 4321 to be the password or change them to something else you will remember easily. (If you do not click on the check boxes a random password will be chosen and advised to you.)

Click Submit and your conference feature will be established.

How to initiate a conference call and invite others.

You, as the Host, enter the conference and bring the other participants into the call:

Steps in Detail:

A.

Dial access number, followed by # from your Phone.

B.

You will hear a beep tone confirming that you have entered the conference room. Now press # to invite a

Participant to the conference room. After hearing the voice prompt ‘Please enter the destination phone number followed by the pound key’, dial the phone number of the person you want to bring into the conference and then press #. After the Participant answers, press # to add this participant to the conference. Alternatively if you dialed the wrong number or the Participant does not answer just press the “*” key and you will be returned to the conference without the Participant.

C.

To invite another participant, press #, wait for prompt, dial next participant’s phone number followed by #, wait for answer and then press # to join them into conference. Repeat this process to invite more participants into the conference. Remember you can use * if you want to return to the conference without the Participant.

Note: You can conference other users by simply dialing their Phone number followed by #. For Participants with regular phone just dial the international dialing prefix followed by their regular telephone number and then press #.

How to have participants to enter the conference room themselves

Any participant that has a MeritPhone can dial our participant access number to enter an active conference him or herself. However the conference call needs to have already been initiated by the Host before the participant can join.

Steps in Detail:

A.

The Host must setup the Participant Password on the “My Account” web site. The Host must then tell the

Participants the conference ID and the Participant password.

B.

Host initiates the Conference by dialing, host access number + #.

C.

Participant dials participant access number + #. Participant will hear the prompt ‘To join a conference, press 1.

To listen to a conference recording, press 2. To access your messages, press 3. To leave a voice mail, press the

* key’. Participant should then press 1 and will hear the prompt “Please enter conference ID”. Participant should then enter the conference ID (Host’s Phone number) followed by #. Finally Participant will hear the prompt “Please enter the conference password followed by the # key” and should then enter the Participant password followed by # to enter the conference.

D.

Other participants can follow the same process as mentioned in C. to join the conference.

Note: Participants who only have a regular phone and are located in USA, Hong Kong or Taiwan can enter the conference from their regular phone by dialing the local access number (contact us for details) and once connected can dial participant access number + # as above. Otherwise the participant can only be invited into the conference by host
