[asterisk-dev] AGI control stream file

[Bryant Zimmerman]

Steven

Thank you for your response. I have not seen any other responses as of yet. 
I appreciate your input and will look into skipping in the file. AGI does 
allow for playback of a file with forward and rewind using the "control 
stream file" method. My real questions was looking into how best to modify 
this AGI function to allow for direct entry into either the rewind or fast 
forward modes in the "control stream file" method.  This method is located 
int the res_agi.c file. It calls the base streamfile functions in the 
underlying asterisk core. This core functions support playback in reverse 
and fast forward using control keys. This is how you can playback e-mail 
messages in both forward and reverse. What I am trying to do is tap into 
this ability without user interaction.

I am a user that is looking to enlist a developer to assist in modifying 
the core asterisk system to support an ability I need. I am toying in the c 
source code but do not feel confident that I could yet make a stable change 
to asterisk myself. Where else should I take questions such as these? Who 
might be open to assisting with this modification?

Steven I do appreciate that you have taken the time to respond to me.

Sincerely 
Bryant Zimmerman

You received a response. Sorry you didn't like the response. Your question
is not for the asterisk-dev list. You are developing something outside
of the asterisk code base. That means you are an asterisk user. 

Liken it to web servers. The apache team develop apache. You might use
apache to make CGI or other scripts, but you are just using apache. Don't
confuse browser operators as users of apache as they don't have a clue
nor do they care about what server you run.

As best I know, there is no ability in asterisk to play a file in anything
other than normal speed and direction. Your "requirements" may just mean 
you
need to do jump based or time based jumps around the playable file. That 
is
how my company implemented ff and rw features in our voice recording
software.
