Creating an H.248 Configuration
From TBwiki
| This article applies to: | Product | Version |
| Tmedia | 2.9, 2.10, 3.0, 3.2 |
After you create the necessary VoIP and TDM NAPs, you can create an H.248 configuration.
1- Click H248 in the navigation panel
2- Create the new configuration:
- Select a transport protocol type
- Enter a public IP address
- Enter a private IP address
- Click Create
3- For 1+1 systems, open the "Advanced Parameters" and then "Behavior" section and make sure this option is checked:
No failover service changes
4- Verify that the "TbgwH248Cfg was successfully created" message appears
