I have configured my asterisk server extension files to make calls to internal extension numbers and also to outbound calls. However, for outbound calls, I need to call to a board room and then dial extension. The moment I make an outbound call and it gets connected, I cannot dial the extension or even if I dial (from soft dialer), it is not sent while the call is still in progress. I tried searching for this kind of setup but could not find. Please advise.
P.S - Using SIP to make calls.
