[Serusers] Click-to-dial working with ATA-186

I was playing around with the ctd.sh script and my SER setup w/ ATA-186
clients.  I got it to work by adding a simple "ACK" to the ctd script
after the INVITE response and before the REFER.  The documentation page
indicates that this ACK happens in the ctd example, but running a
tcpdump/ngrep on the SER machine showed that it never did.

The only problem I have is that when I send an ack through the fifo, it
looks like SER is waiting for a response, so it takes a good 20 seconds or
so before it gives up and moves onto the REFER.

Is there an easy way to convince SER to not wait for a response to an ACK
through the FIFO?  I thought there was a fifo command to do this but
couldn't find one...

Also for anybody who cares, the REFER method works with the ATA-186
firmware 2.16 and higher, but I also created a modified version of the ctd
script that completed the calls using the BYE/Also method that works on
pre-2.16 ATAs.
