Chapter 27 Global PBX Settings

ISG50 User’s Guide

The following table describes the labels in this screen. 

Configuration > PBX > Global > Feature Code 

Group Pickup

This code is used to pick up calls for your extension from a different extension in the same 
authority group.

Call Transfer

This code is used to transfer calls.

Direct Pickup

This code is used to pick up calls for your extension from a different extension. 

Follow Me On

This code is used to turn the Follow Me feature on for this extension. 

Follow Me Off

This code is used to turn the Follow Me feature off for this extension. 

Voice Mail

This code is used to access voice mail on the ISG50.

Mobile Extension 
On

This code is used to activate the mobile extension feature from your regular telephone 
extension. 

Once activated, calls are sent both to your extension and to the phone designated as the 
mobile extension.

For example, if your IP PBX extension has been configured to use your cell phone as a 
mobile extension, you can dial into the ISG50 with your cell phone and then enter this 
code. That tells the ISG50 to send all calls to your extension to your cell phone.

Mobile Extension 
Off

This code is used to turn off the mobile extension feature from your regular telephone 
extension. Calls are no longer sent simultaneously to both your extension and the mobile 
extension; they are sent strictly to your regular extension.

For example, if all calls currently incoming to your extension are sent to your cell phone, 
you can dial into the ISG50 and then enter this code. That tells the ISG50 to stop sending 
calls intended for your extension to your cell phone.

Mobile Extension 
Auto

This code changes the mobile extension feature’s setting from off to on or from on to off. 

For example, if you use this code when the mobile extension feature is turned on, it turns 
it off. If you use this code when the mobile extension feature is turned off, it turns it on.

Call Recording On 
Demand

Use this code to start recording the current call. The on-demand call recording option 
must also be enabled in the call recording setup. See 

Second Dial

This code is used to get a second dial tone. When you enter the Second Dial code from 
your phone, the ISG50 opens a connection to the outside telephone network.

For example, in many office environments you cannot access an outside dial tone unless 
you press “9” or “0” first. A number dialed without such a prefix is considered internal and 
thus routed to the appropriate extension. If that extension does not exist, an error is 
returned.

Leave this field blank if you do not require people using your telephone network to dial a 
specific number to access an outside line.

Note: You only need to enable this function if your phone network is analog-based (such as 

one that uses FXS). Digital phone systems such as SIP and BRI do not require it.

Note: If you enable this function on a digital network, a person does not need to use the 

Second Dial number in conjunction with any phone numbers dialed.

Internal Operator 
(0 or 9)

Use the first field of this code to set which number (0 or 9) internal users dial to reach the 
internal operator. Use the second field to specify the operator’s extension number. The 
extension must already exist in the ISG50.
