more info:
  when I create a /var/spool/asterisk/outgoing/callfile (with multiple 
SIP/xxx&SIP/yyy), the extensions ring.  but when i answer with the 
handset the call does not connect and the other extensions continue ringing.

if i am in the asterisk CLI while the phones are ringing, i can use 'sip 
show channels' and see the extensions in Init: INVITE.

but if i use "channel request hangup <tab>" the session hangs.  I can 
strace these hung rasterisk, but nothing's useful:
# strace -p 25331
Process 25331 attached - interrupt to quit
read(3, ^C <unfinished ...>
Process 25331 detached
# strace -p 26727
Process 26727 attached - interrupt to quit
read(3, ^C <unfinished ...>
Process 26727 detached
# strace -p 26768
Process 26768 attached - interrupt to quit
read(3, ^C <unfinished ...>
Process 26768 detached


the ringing eventually times out, but still no errors on the console.
