Wait a minute, slow down.  I re-installed, same sort of problem:

vici:~ #
vici:~ # asterisk -rx "sip show peers"
Name/username             Host Dyn Forcerport ACL Port     Status

vici:~ #
vici:~ # asterisk -rx "sip show peer testcarrier"

   * Name       : testcarrier
   Secret       : <Set>
   MD5Secret    : <Not set>
   Remote Secret: <Not set>
   Context      : default

I simply want "all" outbound calls to go through a specific context, I 
think, if I understand how the channel passes control to the correct 
context.  I want, or need, an "outbound" context?

I know that the text has an example of ServerA routing through serverB.  
Simply add a line, like:

exten => _9x.,1,Dial(SIP/${EXTEN:1}@babytel_out)


exten => _9x.,1,Dial(${BABY}/${EXTEN:1})

Which just brings me back to...the context for BABY...is...?  BABY is a 
channel variable.  In the above CLI output, the channel variable is 
testcarrier, which has a context of "default".

Each channel variable maps to at most one context?  Many channel 
variables can map to a single context?
