Hello. I am accepting calls from a "SELLER". They are blasting (1) customer call out to multiple "BUYERS" at the same time. First person to ANSWER pays for the call and talks to the customer.
When pointing my DID to a IN-GROUP it appears that all calls are being answered and then routed to my agent. If no agents are available (all on the phone) I set it to play a RINGING audio file but obviously the SELLER still sees this as a answer and is charging me for the call.
Is it possible to setup Vicidial so that when a call comes and if i don't have agents available it sends a SIP 180 (RINGING) or perhaps a BUSY SIP 486 or 600?
I understand this may be more of a Asterisk question but this is over my head and would like your advice. Much appreciated.
