Configure Fax Passthrough
From TBwiki
| This article applies to: | Product | Version |
| Tmedia | 2.10, 3.0, 3.2 | |
| SBC | 3.0, 3.1 |
To enable passthrough:
1. Select Profiles from the navigation menu.
2. Click Create New Profile
3. Enter a name for the Fax Profile.
- Click Fax/Modem Relay to expand the view.
4. Configure the settings:
- Set Detection Mode to Standard.
- Set Relay Mode to Passthrough.
- Check the Switch to FAX relay upon CNG tone option.
- Set Detection type to "Silence Suppression off"
- Verify the the Codec is the same as the remote end.
- Click Create
5. Verify thet the Profile was successfully created message is displayed.
