h323 GW->CUBE->GW call no ringback

Hi all,

i have a cisco h323 gw with 2 fxs phones  connected to it. If a phone calls the othe using its internal number the call goes as expected, the terminating phone rings and the originating phone has its rinback tone.

If I call a phone using a global number, the call is routed through the cube. In this case the originating phone has no ringback.

On the gw  I had to configure for some reason the 'h225 h245-address on-connect'. With this command I can't have the ringback in-band (the gw receives open logical channel after the connect).

How can I force local ringback tone generation on the originating gw?

Is there any configuration I can make preferrably on the CUBE instead of the gw to accomplish this?

Thank you all,

Massimiliano

The running configuration of the h323 gw is:

!

voice call send-alert

voice rtp send-recv

!

voice service voip

fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback pass-through g711alaw

h323

  h225 h245-address on-connect

  h245 tunnel disable

  h245 caps mode restricted

!

As you can see the 'voice call send-alert' command is already configured.

On a wireshark trace I take I can see an alerting go to the CUBE and then back to the gateway with the PI=8 (In-band information or an appropriate pattern is now available).

As per my understanding, the GW would expect the ringback tone from the terminating gw in-band. While I need the originating GW generating the ringback to the calling locally.
