Hi…I m configuring a soft phone on Asteriks …All been set with sip protocol…but multiple calls landing on my soft phone in queue…I want the caller to get a busy tone of the soft phone is in use with another call instead of waiting on queue…where is the configuration i had to change to achieve this…? Pls advice.
Use the DEVICE_STATE function before putting a call to your endpoint. Here’s a pointer to the version 16 page for FUNC_DEVICE_STATE. It should be applicable to many earlier versions, as well.
