Ensure that the fax mode matches between the gateways. In particular, if you leave the CallRestartTimer with the default setting of 5000 ms, the 6624 port uses fax pass-through. To use fax relay, change this value to 1235. The other option is to use fax pass-through on the H323 gateway.
For the Cisco CallManager configuration, perform these steps:
Open up the Cisco CallManager Administration panel.
Click the 24 port Foreign Exchange Station (FXS) blade configured on your Cisco CallManager.
Select the port you are using (port to which your fax has been connected).
Set the CallRestartTimer to 1235 ms. Click Update.
Note: This procedure only applies to skinny gateways, not to H.323 gateways.
If you leave the CallRestartTimer with the default setting of 5000 ms, the port uses fax pass-through. If that is the case, make sure to also use fax pass-through on the H.323 gateway.
To configure the H.323 gateway fax relay, set the fax-rate command to 9600 or 14400 baud in cases where the default G.729 codec is being used, as shown. When using G.711, this command is not required.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
