Hi Anis, The way I do it is using ESL interface, I use it to initiate the call and monitor events, in your case you can monitor events and extract variable information, upon that take action. For example: events = "BACKGROUND_JOB " \ "DETECTED_TONE " \ "CHANNEL_OUTGOING " \ "CHANNEL_CREATE " \ "CHANNEL_ANSWER " \ "CHANNEL_PROGRESS_MEDIA " \ "RECORD_START " \ "CHANNEL_HANGUP " \ "CHAN_NOT_IMPLEMENTED " self.connection.events("plain", events) ev_name = reply.getHeader('Event-Name') Filter in the event where you get your transfer information and filter by call channel... if self.call.uuid == reply.getHeader("Channel-Call-UUID"): variable_variable_transfer_time = reply.getHeader('*variable_transfer_time*') if variable_variable_transfer_time: writedb('transfer_time', variable_variable_transfer_time) Take action like write into DB, file, etc.. Hope it helps You can ping me offline for more details. -Gonzalo On Sat, Oct 8, 2016 at 2:29 PM, Anis Bedhiafi <anis.bedhiafi@e-volut.io> wrote:
Hello
I am working on application using Freeswitch and SIP.js in which I need to detect if the call is being transferred.
The Sip.js application is actually an outbound dialer in which I load a list of phone numbers to call.
The application starts by calling people.
It is interesting to detect voicemail boxes. For that I am using mod_avmd.
My problem is when the other end transfers the call, the sip.js client should know that the current call is being transferred.
Is there a way that the original caller (sip.js client) knows that the call is being transferred?
I was looking at all the channel variables and I found that the RDNIS variable and the transfer_time variable are filled up when there is a transfer.
Is there a way to listen to the channel variables during the call and detect any change? Or is there a better way I can do it?
Thank you for any suggestion.
Anis Bedhiafi
