I've been trying to duplicate your pattern but I get, Invalid extension:
exten => _51,1,Dial(SIP/4781570 at pstn-spa3k-c/ww218)

pstn-spa3k-c is my Sipura-3000 FXO.

This pattern doesn't work either. 
exten => _51,1,Dial(SIP/4781570 at pstn-spa3k-c,30,D(ww218))

According to dial "D" explanation:
'D([digits])'  -- Send DTMF digit string *after* called party has
answered
             but before the bridge. (w=500ms sec pause)

So Sipura FXO answer the phone, and exten. 218 is dialed but before the
call is bridged.  So this will never work.
The 218 supposed to be send after the call is bridged. 

Normal, sequence is, I dial the number, wait for till the system to
answer the call; call is bridged and I dial the extension or account
number etc.
