As a general rule, when dialing an external number you must always dial "9"  first, followed by the telephone number.
Most of the entries needs to be terminated either by using the '#"' (pound) key or by pressing the telephone's 'Send' button.

To call an internal extension, simply dial the 3 digits extension and terminate with the '#' key (or press the send button) Ex: 201#

To place an external call from an extension, you must first dial the '9' to get an external line, followed by the full 10 digits telephone number you  wish to reach and terminate with the '#' key (or 'Send'). Ex:  9 5145551212 #.  

You can also place a call within you own area code  (as defined in the configuration)  by omitting the area code and dialing the number  as a 7 digits number. For instance, if you dial 9 5551212 # the system will insert  your area code in front of the number before placing the call.

If you hear a fast busy tone, it means that all external lines are busy.

The best way to place a long distance call is to dial it as a local call, that is, as a 10 digits number, without pre pending a "1" in front of the number.
Ex:  9 4185551212 #. The system will then use it's database of local prefixes to determinate if the call is local or long distance and will route the call accordingly.

To call a 'tool free' number,  using the 800,  866, 877, 888 prefixes,  you can enter or not the "1" prefix.  That is you can dial "9 1800 5551212 #" or "9 8005551212 #". The system will recognize the 'tool free' number and use the PSTN line in priority.
.

For the international calls, you must dial the 011 prefix as usual. Ex:  "9 011 46701234567 #".

You can force a call to use the conventional line (PSTN) by using the prefix "8" rather than the "9". For example,  8 5145551212 #.
For a long distance call you must then use the "1" prefix as in: Ex: 8 1 418 5551212 #. The "8" prefix indicate to use only the PSTN line.

You can also tell the system to use a VoIP line exclusively by using the "7" prefix instead of the "9". For instance: : 7 5145551212 #.
For a long distance call, you must not enter the "1" prefix.  Ex: 7 4185551212 #. The "7" prefix indicate to the system to use a VoIP line only.

When MARS system are interconnected,  it makes possible to use the external line of a remote system to place a call. For instance the extension "200" on a system A in a given area code can place a call using the external lines of system B located in a different area code. To use a remore server's lines to place a call, preoend the 10 digits telephone number you wish to cal with " * <Server No>" (start followed by the server number (1-4), rather than the usual "9" prefix. For instance, call " *2 418 5551212 # " to dial the given number on server # 2 (Ext: 300-303) from an extension on server # 1 (Ext: 200-203).  In the other direction, call  " *1 514 5551212 # " from an extension on system # 2 (Ex: 300) to use a line on server #1 to place the call.

After having answered the call, enter the sequence   " * 0 " (star followed by zero).. You will then hear "Transfer". Dial the 3 digits number of the extension you wish to transfer the call to. Example: 201. You can then talk with your colleague to announce the call transfer. After you hang-up, the caller will immediately be connected.
Note: The "Transfer Key" of your telephone can only be used to do a "blind" call transfer. (See below.)

For a blind transfer, enter the sequence: " # 0 " (pound followed by zero) (or use the "Transfer" key on your telephone.) and enter the 3 digits number of the extension  you wish to transfer the call to.  Contrary to the supervised transfer, you will be disconnected immediately and the caller will be connected to the destination extension, without allowing you to talk to the the person at the destination extension.

To transfer an incoming call to an external transfer, proceed as explained above with the "# 0" or "* 0" sequence and enter the "9" followed by the 10 digits external number and terminate with "#" (or send). Example: 9 514555 1212 #.

Rather than transferring a call, it can sometimes be useful to "Park" the call and retrieve it from a different extension.
To "park" a call, do a supervised call transfer (as explained above) to the extension number "700". The system will then tell you the extension number to be used to retrieve the call from any other extension. (Usually "701"). To get the parked call back,  enter the parked extension number (701) followed by the pound key ("#"). Ex: 701#
