Can I disable ECM on the DMG 1000/2000
Introduction:
This article provides information about Error Correction Mode (ECM) settings for the Dialogic® 1000 Media Gateways (DMG1000 Gateways) and Dialogic® 2000 Media Gateways (DMG2000 Gateways).
It is only recommended to disable ECM if advised to do so by Dialogic Support. Possible reasons to disable ECM would include:
- Network delays, packet jitter in the network, or if there is evidence of lost network packets.
- If the gateway is used in a fax call, many partial page request (PPRs) may be seen. Many PPRs will make the fax call last longer and it will be more prone to failure.
Procedure:
The DMG1000 Gateways do not allow the user to disable ECM. If the DMG1000 Gateways are used in conjunction with a fax application, it is recommended to disable ECM within the fax application software. Please refer to the fax application software vendor's documentation to determine if ECM can be disabled.
For the DMG2000 Gateways , Error Correction Mode (ECM) can be disabled by going to the following in the web configuration screen
Configuration -> DSP Settings -> Allow T.38 ECM Faxes.
Alternatively if the DMG2000 Gateways are used in conjunction with a fax application software, the fax application software may have the ability to disable ECM. Please refer to the fax application software vendor's documentation to determine if ECM can be disabled.
