G711 Fax + T38 Re-invite Detection Mode (T38R,G711)

Fax Voip T.38 Modem will start in the mode of receiving G711 fax. If T.38 re-invite is received from the other side, Fax Voip switches to T.38 and receives T.38 fax. To set this mode in VOIP Incoming Call Routing rule:

1.     Check G.711 audio fax option.

2.     Uncheck T.38 fax option.

3.     Check Detect T.38 re-invite option.

Notes

• This mode can be used for compatibility with some SIP/H.323 providers and devices.
• This mode can also be used instead of G711 fax mode, see above.
