Maintenance mode - ProSBC and TMG

Useful before_filter "One-Liner" for your routing script: gracefully rejecting all new coming calls.

Graceful Shutdown for new incoming calls

This guide outlines the procedure for isolating a Telcobridges TMG or ProSBC systems to perform bleed off active calls for maintenance period.

This method allows existing calls to finish naturally while elegantly rejecting all new incoming calls with specific cause codes.

🛠 Prerequisites

• Access to the Web User Interface.

• Permissions to edit and activate Routing Scripts.

• A defined configuration for testing. Our example: (e.g., MSGC_TG_V11_DaveTest).

📝 Step 1: Modify the Routing Script

To stop new calls from being processed, you must add a before filter to your main simple_routing script.rb file.

1. Navigate and click >> Routing Scripts left-hand side of the menu.

2. Click on simple_routing.rb.

1. Locate the class SimpleRouting < BaseRouting definition line within the script.

2. Add the following line as a before_filter: right below last Include line.

before_filter :proc => proc { |p| raise RoutingException, :no_circuit_available }

1. Scroll down to the bottom of the simple_routing.rb script page and save.

1. Validate the configuration change. Activate the configuration change.

Note: Activation of new configuration will NOT terminate active calls.

1. Monitor Call Trace Page

8. Monitor Call Status Page

Quick Notes:

Insert a # character in front the before_filter to deactivate the call rejection progress.

## before_filter :proc => proc { |p| raise RoutingException, :no_circuit_available }

You can also modify your cause code to your preference. no_circuit_available

before_filter :proc => proc { |p| raise RoutingException, :no_circuit_available }

Reaon Cause Mapping definitions can be found in Web UI >> Profiles >> "Selected Profile" >> Edit Reason Cause Mapping

Activate Call rejection. before_script is working...

Deactivate Call rejection. before_script is not-working...

Repeat Step 5 and 6. Save Script. Validate and Activate new configuration.
