How to add additional VoIP resources after a license upgrade
If the number of VoIP resources has increased following a license upgrade, or if there is an incorrect number of channels in the existing configuration, the number of IP channels configured in a VoIP module in the "Packet Facility" object on the Dialogic® IMG 2020 Integrated Media Gateway (IMG 2020) may need to be changed.
This article describes the steps to delete and re-add the packet facility object with correct number of channels.
1- First save the current configuration using File > Save in the WebUI.
2- Delete all "Node Assoc:" (Node Association) objects from all SIP gateways in Channel groups and make sure there are no remaining "Node Assoc" objects in Channel Groups > Channel Group (SIP) > IP Network Element > Node Association.
3- Click on "Channel Groups> Download resource tables".
4- Delete Packet Facility (e.g., Packet_Facility1) object from the IMG 2020.
5- Re-add the Packet Facility object under the IMG 2020 with the correct number of IP channels according to the IMG 2020's IP Ports license.
6- Re-add all "Node Assoc:" under each SIP gateway for the IMG 2020.
7- Click on "Channel Groups> Download resource tables".
8- Verify that call traffic is processed and IP channels are used in calls, and that the EMS connection state is "connected-in-sync".
Important: These steps should be scheduled during a maintenance window as the procedure will disconnect all ongoing IP calls on the IMG 2020 after the Packet Facility object is deleted.
- The "Number of Channels" in the Packet Facility object should be the same as the number of IP Ports in the "License Info" object.
- Take extra care when deleting the Packet Facility object and make sure that there are no "Node Assoc:" objects remaining before proceeding with deleting the Packet Facility object.
- Deleting a Packet Facility object while there is still an existing "Node Assoc:" object may cause issues on the IMG 2020. The WebUI status may show “EMS: Not Connected - Sync Unknown - Version Unknown” which will require re-loading the backup configuration in order to roll back to the previous state.
