I have not played with any zapata FXS devices yet but I found this on the zapata.conf wiki page under Analog Handset Features / immediate
"when you lift an FXS handset, the Zaptel driver provides you a dialtone and listens for digits that you dial, passing them on to Asterisk." I comprehend this as, you dial and the DTMF is immediately passed to Asteisk and your context of extensions.conf. If have designed your extensions.conf dialplan without any pattern matching that could delay a user dialing extension 510, it should go right through. This maybe an incorrect assumption.
