Thank you for your kind feed back.
Could you pls tell about the following ?
1- QUINTUM box generates locally the ring back tone after reception of ALERT message (encapsulated in H323)
2- OR does it just let pass the ring back tone that is generated by the remote CISCO 5300 or remote PSTN Switch for example ?
3- Is there anyway the Quintum box can generate locally the ring back tone, what ever the situation (even without reception of the ALERT msg), such that the caller does not panick & wait until reply of the called part ?
