Unfortunately, this is one of those cases where the AMI output is the
same as the CLI output, which makes it difficult to parse.  (Regular
expressions can help, but you obviously have an aversion to them, so
we'll use another method.) As long as your IAX peer names are shorter
than 16 characters, you can use a trick I've used for a while... first
get the list of iax2 peer names:

Action: IAXPeers
ActionID: 987325918659161

ActionID: 987325918659161
Name/Username    Host                 Mask             Port
Status    
flibbertygibbit  (Unspecified)   (D)  255.255.255.255  0
Unmonitored
demo/asterisk    216.207.245.47  (S)  255.255.255.255  4569
Unmonitored
2 iax2 peers [0 online, 0 offline, 2 unmonitored]

and break on the first space or forward slash.  Once I have an array of
IAX peer names, I use the Command action to run "iax2 show peer
<peername>" on each of the IAX peers, like this:

Action: Command
Command: iax2 show peer flibbertygibbit
ActionID: 762315185916555

Response: Follows
Privilege: Command
ActionID: 762315185916555


  * Name       : flibbertygibbit
  Secret       : <Not set>
  Context      : blah
  Mailbox      : 
  Dynamic      : Yes
  Callerid     : "" <>
  Expire       : -1
  ACL          : No
  Addr->IP     : (Unspecified) Port 0
  Defaddr->IP  : 0.0.0.0 Port 4569
  Username     : hullabaloo
  Codecs       : 0xe703 (g723|gsm|g729|speex|ilbc)
  Codec Order  : (none)
  Status       : Unmonitored
  Qualify      : every 60000ms when OK, every 10000ms when UNREACHABLE
(sample smoothing Off)

--END COMMAND--

That output is obviously somewhat easier to parse, although it's not
perfect either.  Hopefully the Asterisk development community will
eventually get around to rewriting much of the AMI actions to make their
output easier for programs to parse.
