Abstract: In one embodiment, a method includes receiving a media signal associated with a session established based on a session request. The session request is defined at a session exchange device associated with a media over internet protocol (MoIP) network. The method also includes sending a portion of the media signal to a dual-tone multi-frequency (DTMF) analysis module during a sampling time period after a non-sampling time period.

Abstract: In one embodiment, a method includes receiving a first internet protocol (IP) packet having information associated with a dual-tone multi-frequency (DTMF) signal. The information of the first IP packet is configured based on a protocol associated with a first layer of a media over internet protocol (MoIP) network. The first IP packet is associated with a destination endpoint. The method also includes producing a second IP packet having information associated with the DTMF signal. The information of the second IP packet is configured based on a protocol associated with a second layer of the MoIP network and a DTMF conversion policy associated with the destination endpoint. The second layer is different than the first layer.

Abstract: Methods, systems, and computer program products for adaptively adjusting a registration interval of an endpoint are provided. In an embodiment of the subject matter disclosed herein, a method of adaptively adjusting a registration interval of an endpoint comprises determining a registration interval for an endpoint associated with a binding defined at a network address translation device. The method also comprises determining a stability of the binding based on a message received from the endpoint. Further, the method comprises adjusting the registration interval for the endpoint based on the determined stability of the binding. A message can be sent to the endpoint for indicating the adjusted registration interval.
