Long idle time before it dials out

I do use analog phone connected to SIPURA 2000. Whenever I dial there is an idle time I think a minute after I dial the last digit before it make call.
I notice that asterisk seems don’t know that I already dialed the last digit. As of now I do use # to terminate the dial to avoid idle time. Please advise how to resolve this.

Thank you very much.
