Well, if you have soxi installed (Linux, of course) then you could always use a system call to grab the file length. For kicks I whipped up a proof of concept dial plan to demonstrate how it could work. If anyone finds it useful please let me know and I'll wikify it. -MC <extension name="soxi sound file length"> <condition field="destination_number" expression="^(9904)$"> <action application="answer"/> <action application="sleep" data="500"/> <action application="set" data="sound_file=${sounds_dir}/music/8000/danza-espanola-op-37-h-142-xii-arabesca.wav"/> <action application="set" data="file_length=${system soxi -D ${sound_file} | tr -d '\\n' }"/> <action application="log" data="INFO Sound file length is '${file_length}'"/> <action application="set" data="file_length=${expr(ceil(${file_length}))}"/> <action application="log" data="INFO Sound file length is '${file_length}'"/> <action application="say" data="en number pronounced ${file_length}"/> <action application="playback" data="time/seconds.wav"/> </condition> </extension> On Mon, Jul 23, 2012 at 9:09 AM, Alexandre Fiori <fiorix@gmail.com> wrote:

that's the problem, I don't know the length, but playback does :)

thanks anyway

If you know the length of the file then you could use sched_api to schedule something. For example, if you know that your file is 12 seconds long you could do something like this:

sched_api +9 none uuid_broadcast <uuid> <app>::<args> bleg

Check out both of these on the wiki - there's a lot that these can do. -MC

Excellent! Do you mind finding a spot up on the wiki for this? -MC On Mon, Jul 23, 2012 at 4:01 PM, Alexandre Fiori <fiorix@gmail.com> wrote:

Amazing. This is exactly what I was looking for, and couldn't figure out how to do. Thank you!

Just found this http://lists.freeswitch.org/pipermail/freeswitch-users/2011-May/072338.html Which seems a useful tip

Apologies about the formatting of that - quite horrible. Not sure why, though. Let's try again...

<condition field="dest_num" expression="^\+" inline="true"> <action application="log" data="WARNING Begins with +"/> <action application="set" data="dest_num=00${dest_num:1}" inline="true"/> <action application="log" data="WARNING dest_num now ${dest_num}" /> </condition>

Although it seems to be doing the right thing, it isn't. Lower down the file, I have

<condition field="destination_number" expression="^(\d{8}.*)"> <action application="bridge" data="[tenant_id=${tenant_id},a_ext=${a_ext},b_ext=${b_ext},origination_callee_id_number=$1,origination_caller_id_number=${ani_prefix}${ani}]sofia/internal/8980000000002$1@193.105.54.10"/>

<anti-action application="log" data="WARNING ${destination_number} not a long number"/> </condition>

And when I place a call to +44123456789 the log records
