OVERVIEW

Protel LTS allows for complete flexibility in programming caller ID overrides and trunk selection.  This can be set for any dial pattern, but is most commonly used to create rules for 911 calls.  Federal 911 guidelines are now requiring the caller ID location information to be much more accurate than in the past.  The tools in Protel LTS allow you to send location-specific caller IDs, assignable by extension.  This means you can send a company-wide caller ID for normal calls, but a specific suite, floor number, building, etc. when dialing 911.  The trunk assignment tool can be used to specify a certain trunk for 911 calls.  An example of this would be a company that uses PRI for normal calling, but since most PRIs are locked to a single pilot caller ID, 911 calls need to use an alternate trunk that accommodates a location-specific caller ID, such as a SIP trunk or a POTS line.  The caller ID override and the trunk dialing tools can be used independently, or in tandem.


CALLER ID OVERRIDE

Destination Specific Caller ID.   This tool is available in the Trunks and Configurations section of the PBX.  For each extension user that needs to override caller ID, you will need to define the dialing pattern that triggers the override and enter the desired caller ID that will be sent when that dialing pattern is detected.

1. In the Call Destination field, enter 911.  NOTE: any number string can be entered here, and the override will be applied for that specific dial.

2. From the drop down menu, select the extension that needs the override, or select “All” 

3. In the Caller ID field, enter the 10 digit number that you want that extension to send when it calls 911.  This can be any number; it does not have to be a DID that is registered in the PBX.

4. Click on the Add button   

Each time you add a dialing rule, it is added to the list displayed on the page. To remove a rule, just click on the X button next to it.  If you need to edit a rule, you will need to delete it and re-enter it.

 

TRUNK OVERRIDE

Specify Trunk for Destinations.   This tool is also available in the Trunks and Configurations section of the PBX.  If you need 911 calls to go out on a trunk other than the trunk that an extension would normally use, this is where you define that rule

1. In the Call Destination field, enter 911.  NOTE: any number string can be entered here, and the trunk override will be applied for that specific dial.

2. From the drop down menu, select the extension that needs the override, or select “All” 

3. From the next drop down menu, select the trunk to use.

4. If the designated trunk is down, and you want the PBX to attempt the 911 call using its default trunk settings, check the “Allow Standard Trunks Also” box.  If you want the 911 call to ONLY use the override trunk, do not check this box.  If this box is not checked, and the override trunk is down, the 911 call will fail also.

5. Click on the “Add” button.

Each time you add a trunk rule, it is added to the list displayed on the page. To remove a rule, just click on the X button next to it.  If you need to edit a rule, you will need to delete it and re-enter it.

Remember to execute a reload after making any changes to these rules.


USING SIP FOR e911

If the customer is using PRI, adding a low-cost SIP trunk allows you to send location-specific caller IDs.  nexMatrix Telecom can provide you with a trunk, and can assign new DIDs that you can register with our e911 provider for each emergency response address.  Those DIDs do not need to be published or used for inbound calling, but are only used as caller ID in the event of a 911 emergency.
