Hello - we have been testing SIP Trunks with Asterisk for origination and have been successful in getting a telephone user to dial in and take part in our application's conference calls. We used Twilio SIP Trunking as our test - however they charge per minute for inbound calls. We are looking for a flat fee for unlimited minutes in order to control our costs.
Essentially - we need one number with a lot of channels, and no cost per minute. It seems like a lot of channelized plans in the US are around $25 a channel. That gets expensive quick. $100 a month for the ability to have only 4 concurrent calls seems awful high.
We have also been looking at DID numbers with multiple channels as they seem to be a lot less per month, however most of the sites I end up at (www.buydidnumber.com, etc.) look less than reputable.
Does anyone have any advice for a way to provide dial-in services for say 50 to 100 concurrent users without having to pay $25 per channel?
Thanks in advance for any advice!
matt
