Posted: Tue Jun 03, 2008 8:21 am Post subject: [asterisk-users] Any reason to not use AEL? (Also, MixMoni

I am building a new Asterisk server here at the office, and I'm wondering if there are any downsides to creating my dialplan with AEL. It seems more intuitive (to me), but I'm not sure if there are any pitfalls I need to be aware of first. We use this for internal extensions, 8 pots lines, and our answering service which gets about 500 incoming calls a day down our T1. Also, one more quick question too: Currently I'm using MixMonitor to record incoming calls. The problem, however, is once calls are transferred, recording stops. Is it possible to keep recording after a call is transferred, and if so, how? Thanks in advance, Jay

AEL in 1.4 was the first version of AEL that most people consider
"stable". Since not many people uses AEL, you won't get nearly as much
(if any) community support compared to if you are using the non-AEL syntax.

I use AEL in almost everything I do and work a lot with Steve Murphy to
work out any issues I have found with it. In Asterisk 1.4 AEL is VERY
solid. The only thing you need to watch for is falling into some basic
"traps" like calling ${EXTEN} from within a switch (the AEL compiler
uses sw-xxxx extensions for case instances). In order to easier see
what the compiler puts out, I asked Steve to add the -w option to
AELPARSE which writes a file (extensions.conf.aeldump) which is . much
easier to read than doing a "dialplan show [context]".

Anyway, I'll be more than happy to help with any issues you may have
with AEL. I'm even working on writing a little book or at least series
of articles on AEL

This has been fixed in latest versions of 1.4

Generally AEL is good and nice, I haven't yet been using it alone, I
use aelparse in dump mode to create extensions.conf. This allows me to
check any warnings/errors before actually loading anything in
asterisk. However I plan to switch into pure AEL later.

However there's one suggestion - avoid using "macro" syntax if you
plan to use the same macros from Realtime or AGI. I recently tested
that with 1.6 and it's behavior is changed - so you'll have to change
your AGI and Realtime generation scripts in order for this to work
with 1.6. As developers replied to me, this kind of usage is just "not
supported". Generally - avoid assumptions that dump generated from
AELparse will work on other versions.

Btw, you can also use combination of both, have some part of dialplan
in extensions.conf file and some in AEL.

Regards,
Atis

Not sure what you mean, but if you mean realtime dialplan, then no, you
can't use AEL for that. However, we might wish to see if Murf knows if
this can be done.

This should already be solved in the latest release. The extension will
be saved in an alternate variable, and references to ${EXTEN} below
a switch will be converted to use that alternate variable.

So do you think that it would be nice to have Asterisk dump the dialplan
in extensions.conf format? e.g. if there were a command such as
'dialplan dump [context]'?

This would allow you to dump the dialplan from a running asterisk using
'asterisk -rx', which is now actually more reliable.

extensions.conf does not show the extra "source" column that 'dialplan show'
has.

Actually, no they're not converted to the alternate variable. Guess I
should contact Murf, because now that I think of it I had mentioned this
to Murf before I think.

They are on 1.4.19, but this works invisible to user:

exten => _X.,76,Set(~~EXTEN~~=${EXTEN})
exten => _X.,77,Goto(sw-98-${DIALSTATUS}|10)
exten => _X.,78,NoOp(Finish switch-if-if-local_dial-95-97-9 Cool

exten => _X.,79,Goto(103)

Oh, I think AEL is a great idea. I expect we will start migrating our
macros into AEL when we upgrade to 1.6 (maybe 6 mo - 1 yr from now).
I'll start with our extensive, spaghetti code macros. I doubt we will
ever migrate *everything* to AEL, no need to with the way we have our
extensions.conf setup. i.e. Set channel variables, run macro.

Yes, but if you call ${EXTEN} within the switch, it does not (at least
on my Asterisk 1.4.20 system) jump transparently to ${~~EXTEN~~} it
still attempts to use ${EXTEN}.

[new_test]
exten => _X.,1,Goto(sw-24-${CHANNEL}|10)
exten => _X.,2,NoOp(Finish switch-new_test-24)
exten => _sw-24-.,10,Goto(${EXTEN}|tests)
exten => sw-24-,10,Goto(sw-24-.|10)

AEL Code:
context new_test {
_X. => {
switch(${CHANNEL}) {
default:
jump ${EXTEN},tests;
}
}
}
