Using Your Telephone

Your new telephone is a state of the art IP Telephone instrument. It is manufactured by Grandstream.

Grandstream is a premier brand in Global VoIP telecommunications.

Making a Call

The Grandstream phone is a high quality speaker phone. To make a hands free call, simply dial the number followed by the “send” key. To hang up, press the speaker button or end call soft key. Outside calls require dialing “9” + the number.

To place a call using the handset, Pick up the handset and dial the number. Press the “send” key.

Answering Calls

If your phone rings, you answer it by simply lifting the handset, or you may press the SPEAKER key to answer the call using the speakerphone function.

Placing Callers on HOLD

The HOLD button on each phone is a private function. If you place a call on hold using the HOLD button, only your extension can retrieve that call. This allows each user to place calls on hold without someone accidentally picking up the wrong call.

Placing Callers on PARK

Callers can be placed on Park locations to facilitate other users picking up the call. After answering the call, you press Transfer + PARK, and then hang up. You may then call another user to inform them of the call and the PARK Location number, and they pick up by pressing the PARK Location Button.

If no park location is being used, the system places the first call to be parked on 71. A second call being parked before the first one is picked up will be placed on 72, etc.

Transferring Callers to another extension

Callers can be transferred directly to another user by pressing the Transfer button and then pressing the button for the extension you are transferring to.

To create a three party conference

Call the first party, press CONF, and then call the second party. When the called party answers, press CONF again to join all three parties.

For larger conference calls

To create a Conference of more than 3 people, it is best to use meet-me-conferencing. Callers can be transferred into the conference room by anyone or they can call into the conference room directly. You have two conference rooms set up. The conference rooms can be accessed by dialing 500 or 501. The default password to enter the conference is 1234. The size of the conference is limited by the number of lines.

To transfer a user into a conference, first announce to the caller that they will need to enter 1234 when prompted for a PIN number, and then press TRANSFER + 500 + SEND to send the caller into the Conference Bridge.

Adjusting Volume levels

The Up Arrow and Down Arrow keys are used to adjust the volume of the phone based on current phone state. If the phone is idle, the Arrow Keys control Menu Functions once the Menu is entered. From this menu, you can navigate to Preferences and then Ring Volume to adjust the Ringer Volume. If the handset is off hook, the volume control changes the handset volume. If the phone is engaged in a Speaker Call, the volume control changes the Speaker Volume.

Soft Keys

The soft keys change when the telephone is in different states. On hook, off hook, call connected or call hung up will all result in different soft key options.

Voice Call

To make a voice call pickup or depress the speaker key, dial *80 plus the extensions number then press the “dial” or “send” keys. You may then make your desired announcement. The called party may answer back hands free or pickup the handset to make the call private.

Mailbox Overview

The PBX-IQ IP PBX includes a highly flexible, powerful voice mail system. Among the features that are included in the voice mail systems are:

Three different types of greetings

Voice Mail sent to email including a .wav file containing the complete message.

An organization system called “Folders” to organize saved messages

Password protected mailbox access

Audible recording menu to record and re–record mailbox greetings


A mailbox greeting is a message for you to inform the caller that you are away from your desk or busy on another call.

There are three types of Greetings:

Not Available Greeting

– Played when your phone is unanswered

Hello, this is Mark; I am not able to answer your call right now. Please leave a detailed message and a number where I can reach you, and I’ll call you back as soon as I am able.

Busy Greeting

– Played when your extension is busy

Hello, this is Mark, I am currently on the phone and not able to take your call right now; please leave me a detailed message and I will call you back as soon as I can.

Temporary Greeting

– Played whenever it is recorded

The temporary greeting is played as a replacement for your other greetings. When the situation warrants a greeting to inform your callers of something different than your regular greetings; record a temporary greeting and it will replace the others while it is active.

Sample temporary greeting – Hello this is Mark; I am on vacation with limited access to messages. Please call extension 1500 and speak to Mary with any matters that need immediate attention. I will return on Monday, February 24.

Default Greetings

If you do not record any greetings, PBX-IQ will play a set of default greetings depending on the status of your extension. Be sure to record your name so your greeting will be a little more elegant. If you do not record your name, the default greeting will say “the person at extension (your extension number) is not available”.

If you record your name the greeting will say “Mark Smith” is not available…”


The PBX-IQ IP PBX allows you to save and organize your messages into folders.

There are five folders:

0 New

1 Old

2 Work

3 Family

4 Friends

# Cancel
