[asterisk-users] Hanging up all call on a device via CLI/AMI/AGI

[Forrest Vodden]

Hello, never posted to a mailing list before. I've been trying to work out this problem for quite awhile now. I have a PHP script which is run whenever an emergency situation happens. The script connects to the AMI and originates calls to previously defined "emergency" extensions. I'm looking for a way to disconnect all calls on a device if it is in use, in order to deliver the message. I cannot use SoftHangup with the 'a' option within the dial plan, because if the device that is called is busy, then the context is never hit. It doesn't appear that their is a way within the AMI or using AGI or even within the CLI to disconnect all calls on a device, only is you know the entire channel name.

For instance, from the CLI, running 'soft hangup SIP/250-ab627038' will disconnect the channel successfully. But the problem is, I have no way of finding out the full channel name from within my my script using the AMI. The only possibility I see is running the "show channels" CLI command via the AMI Command action, grabbing the resulting list and parsing the Channel Name column before the script begins calling extensions. Then before each extension is called, check to see if the extension exists in the retrieved channel list. If so, disconnect it.

Anyways, it seems odd to me that the 'a' option is available from within the dial plan, but not anywhere else. That would be the simplest approach to this.

Any help is greatly appreciated. Thanks.
