As i can see there is both h323 and isdn alerting messages in this debug, but why there is no ringback tone?...

Also i have same h323 GW in another location (with almost same config), which is connected to CUCM to and i've ringback tone with this GW.

Can you help please...

Ringback tone issue CUCM to H.323-PSTN GW

Hi,

As you said that you have already followed the instructions as per your attachment but still i would suggest you to implement it once as per the Amine has suggested.

If still it doesn't work then please take one successfull debug of ring back tone along with the RTMT detailed trace and try to compare with the unsuccessful one.

Regards, Nishant Savalia
