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.

Methods and apparatus for dual-tone multi-frequency signal analysis within a media over internet protocol network

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.
