Hi Abdul,<br><br>More information about your setup would be helpful to resolve your problem. RBT could be a locally generated tone at the endpoint as a result of SIP provisonal messages. Are you sure that this RBT is played from the remotes Telecom switch? Any NAT is between? How are you terminating onto the PSTN, PCI cards? gateway?
