[asterisk-users] Issues with Local Channel
Hello, I don't really understand how channel Local works. I need that asterisk initiate a call and get some data (DTMF). So to do that I've created this dialplan : ; extensions.conf - the Asterisk dial plan ; [general] static=yes writeprotect=no clearglobalvars=no [dtmf] exten => 1,1,Verbose(Get User ID) exten => 1,n,Dial(dahdi/1/99999999,120,G(read^1^1)) exten => 1,n,Hangup() [read] exten => 1,1,Hangup() exten => 1,n,Read(data,play-msg,4,,2,15) exten => 1,n,Verbose("${data}") exten => 1,n,AGI(send_data.py,${data}) exten => 1,n,Hangup() File: test.call Channel: Local/1 at dtmf Application: NoOp I've create a file name test.call and then move the call file to the dir /var/spool/asterisk/outgoing/. Some issues I've had, the option G, in the Dial function don't wait the user answer the call to follow the dialplan. Is this rigth? Is this because I have used a Local Channel? Are better way to do that? Regards, S idarta Oliveira -------------- next part -------------- An HTML attachment was scrubbed...

Local channels behave like an endpoint. So instead of a sip phone picking up the call, asterisk is picking up the call. Instead of someone speaking into a sip phone, asterisk can play tracks, or record digits, etc. You need to make sure that the call does not end before you're done with your local channel. Your current use is incorrect and your call is going to hang up before it does much of anything. Channel: Local/1 at dtmf Application: NoOp This is guaranteed to not work... asterisk will spawn the local channel one one leg, lets call it the source leg, and it will run the application NoOp on the destination leg. The NoOp will run, there is then no more dialplan to run, so the call will be hung up. Also... using the G option to dial, is probably not what you want. You must think of a local channel as an end point. I'm not sure if this will get you exactly what you want, but it should get you further along the path. # destination dialplan [read] exten => 1,1,Answer() exten => 1,n,Read(data,play-msg,4,,2,15) exten => 1,n,Verbose("${data}") exten => 1,n,AGI(send_data.py,${data}) exten => 1,n,Hangup() -- Note that timeout is in milliseconds Action: Originate Channel: DAHDI/1/99999999 Context: read Exten: 1 Priority: 1 Timeout: 120000 This isn't using the local channel, but instead uses straight dialplan. Asterisk will wait for the "source leg", 99999999 to answer, and once it does, it will execute [read] Here's how to do it with local channels. # source leg [dialout] exten => 1,1,Dial(dahdi/1/99999999,120) exten => 1,n,Hangup() # destination leg [read] exten => 1,1,Answer() exten => 1,n,Read(data,play-msg,4,,2,15) exten => 1,n,Verbose("${data}") exten => 1,n,AGI(send_data.py,${data}) exten => 1,n,Hangup() Action: Originate Channel: Local/1 at dialout Context: read Exten: 1 Priority: 1 Timeout: 120000 Note, that the timeout applies to waiting for the Channel "source leg", endpoint to pick up. If you put the timeout to say 1000, (1 second), asterisk will kill the call before the Dial() timeout of 120 seconds hit.
