After examining memory usage and our code, I coded up this application
entirely in asterisk and let 'er run for a bit.  To my surprise, it
exhibited the same problem.  Here's what I did:

[intrunk]
; match any 10 digit dialed, and prepend a 1 for the country code
exten=_XXXXXXXXXX,1,Prefix,1
; dial in default context with extension converted from above
exten=_1XXXXXXXXXX,2,Goto,default|${EXTEN}|1

[default]
exten=_17005559248,1,Goto(ccmenu,s,1)
exten=_1XXXXXX4636,1,Goto(ccmenu,s,1)
exten=_1XXXXXX6338,1,Goto(ccmenu,s,1)

[ccmenu]
exten=s,1,Ringing
exten=s,2,Wait,2
exten=s,3,BackGround(5045)
exten=s,4,Goto,outtrunk|17005554223|1   ; if they just wait
exten=_X,1,Goto,outtrunk|17005554223|1  ; if they press 0-9
exten=_*,1,Goto,outtrunk|17005554223|1  ; if they press *
exten=_#,1,Goto,outtrunk|17005554223|1  ; if they press #

[outtrunk]
; match any US, and strip leading 1 off
exten=_1XXXXXXXXXX,1,StripMSD,1 
; dial outbound on trunk group 1
exten=_XXXXXXXXXX,2,Dial,Zap/g1/${EXTEN}


Ran fine for the first few hundred calls, then the transfer still
happened, but no audio was passed in either direction.  Doing a
'restart now' makes it work again for another few hundred calls.
