Asterisk SIP Trunk Issue

We are having some issue with OLD Analogue Phones. The call is answering right after the dial is initiated. So our customers are being billed for hearing the ringing tone. The caller gets the 200-OK message at the beginning of the call.

None of above is expected. We need our customers hear fake Ring back, not billed & their CDR not updated as answered until the call is picked up by a real human.

That's pretty much it. Please read it carefully and bid if you want. Budget $100. If you have any question then feel free to ask after reading the details I already provided.

You can put fake ring in early media in that way your customer will hear ring before call is established and it will not be billed. Cheers, Nikola

There is no option to detect answer on asterisk PBX in analog lines unless your telco enable the polarity service. Please ask them to enable polarity service in analog lines, or go with PRI or SIP trunks if they have.
