6. The most important difference is that if you want to tweak any of the behavior, it is much easier to do so in the Asterisk dialplan as opposed to modifying the C code of the FollowMe() application. Here is what happens when someone dials 7001 to reach Russell: exten => 7001,1,Progress() The Progress() application is used for telephony signaling. We do not want to answer the call yet, but we want to start playing audio. This is often referred to as early media in a phone call. The use of Progress() in the dialplan maps to sending a 183 Session Progress request in SIP: same => n,Playback(followme/pls-hold-while-try,noanswer) Now that we have told the calling channel to expect early media, we are going to play a prompt without answering the call.

Give up after 20 seconds. ; number = 12565551212,20 [leif] context = trusted number = 7102,20 number = 12565559898,20 Now create extensions in the dialplan that will utilize the FollowMe() application to locate the called party: [public_extensions] exten => 7001,1,FollowMe(russell) exten => 7002,1,FollowMe(leif) [trusted] exten => 7101,1,Dial(SIP/russell_desk) exten => 7102,1,Dial(SIP/leif_desk) exten => _1NXXNXXXXXX,1,Dial(SIP/${NUMBER}@outbound_provider) Discussion Admittedly, everything that the FollowMe() application does for you can be implemented directly in the dialplan.

Wav) In this example, a caller would dial 500 to initiate the paging process. The Record() application would allow them to record their announcement to a file. The recording will end and be saved to disk when the caller presses the # key on their phone. The paging process can be canceled from this point by just hanging up. Next, the Origi nate() application starts a new call. On one end of the call is a Local channel, which is executing a short extension that just plays back the recording that was just left.
