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
!
[...]
dial-peer voice 1 pots
description Numerazione 911
destination-pattern 27911

port 0/0/0
!
dial-peer voice 2 voip

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.
