We running a calling card system, we are encountering a problem that l have been trying to solve without much success. Our system consist of Asterisk server with Digium TE210P interface. The system work find if only two concurrent user are on it, although it should be able to accommodate up to 5O simultaneous user but when the third user dial in the system send “Channel Unavailable” or “Circult Busy” message, what could be the problem here. Any help will be greatly appreciated.
