Need help configuring the following dial plan.  To make a PSTN call I have to call extension 510 or 520, then bridge and answer the call to get a dial tone.  Then dial the outgoing number.  My problem is that the send_dtmf  command does not wait 1 second (W command) after the answer.  It seems to delay the answer command by 1 second.   How do I get the call to answer and then wait 1 second and then send /dial the number?

Thanks
