Hi everyone,
I want to set up max time out for each extension. Such as, when incoming come, extension ring for 10s then automatic hangup.
For 14.0.13.40 version, I tried Ring Time/ Ringer Volume Override/ Call Forward Ring Time,… but it didn’t work.
Please help, 
Advanced Settings → Dialplan and Operational section → Ringtime Default
You can’t ‘hang up’ a call that was never connected. When Ring Time expires, the call is sent to voicemail, but if that is disabled, the timeout is ignored. I assume that upon timer expiry, you want Asterisk to cancel the call to the destination and report an error status to the calling device or trunk. Why? Do you want to do this for both internal and external calls?
Thank you. Is that apply to everysingle extension or all of them ?
For example, if I have 100 phone numbers, instead of manually dialing each number, I can create a list of numbers for automated dialing. Agents simply need to pick up the phone when a connection is established with a customer. This means when an outbound call is answered, it will be connected to the next available extension. If an extension doesn’t answer within 10 seconds, the call will be transferred to the next available extension. (Note: I haven’t set up a queue because the extensions don’t belong to a group.
Its done, I can setup max waiting time for each extension via “Ring Time” option.
The problem is, I had to create a new extension to do that. The extension i’m using can’t do that, both of them have the same config.
I have no idea
