Modifying FAX Relay Profile Settings

Applies to versions: 2.6, v2.7

To configure FAX Relay settings, do the following:

1- Click Fax Relay in the Editing Profile window, to display the customizable options.

2- Modify settings as required.

3- To configure NSE, check the Use NSE checkbox.

NOTE:

If NSE exchange is possible (negociated in the SDP), the switch to passthrough will happen in the RTP stream and no longer wiil occur with a SIP re-INVITE. This implementation of NSE currently only supports a switch to passthrough, which means that you can have NSE packets switching to T.38.
