[Asterisk-Users] FAST BUSY on Back to back ZAP outgoing calls

Hello, I have a TDM400P with 2x2 configuration of FXOs and FXSs.  I set
a test extension of '444' to dial out a specific zap trunk and call a
local #.  First time I call out to '444' everything works fine.  If I
hang up the call, and within 10 seconds dial the same number again, I
get a fast busy.  Seems it isn't letting go of the trunk or something,
and I don't have a butt-set to listen in on it while its doing what it
does.  I'm dialing from a standard US pots line with no call waiting,
call forwarding, or caller ID.  Bare-bones.   Here is the
extensions.conf and Zapata.conf section, as well as the relevant error
lines:

 

Extensions.conf

exten => 444,1,Dial(Zap/4/6718688)

exten => 444,2,Hangup

 

Zapata.conf

context=pstn7469

echocancel=no

signalling=fxs_ks

channel => 4
