METHODS & APPARATUS FOR DUAL-TONE MULTI-FREQUENCY SIGNAL ANALYSIS WITHIN A MEDIA OVER INTERNET PROTOCOL NETWORK

摘要

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.
