Hi,

It’s been a very long time since I dealt with a along lines. Does anyone know if there is a way to “pass though” a hook flash? I am working on a project where there will be one FXS and one FXO. I want if there is call waiting for the phone connected to the FXS to be able to hit the hook and have that sent back out on the FXO port.

TIA

  • Since this function is handled by the ATA, you would have to look there (or post details) for something ATA specific. In general I don’t think so, hook flash just puts one channel on hold a creates/answers another. But, you may be able to script the functionality you need it in the Ast dialplan.

  • Most ATAs have the capability of sending hook flashes to the server. That’s how all mine are configured, and Asterisk handles hook flashes. As of 18.4/16.17, there is a Flash AMI event as well that can be used to listen for these and do something configurable.
