[Freeswitch-users] Documentation Questions - updating wiki, channel variables

Fri Nov 2 17:09:49 PDT 2007

there are also cases where switch_channel_set_variable is being called so you may want to cross reference those too

also if you route call to the info app you can see many magic variables. some of these may be dups but you can factor them into the raw list.

sip_from_user
sip_from_port
sip_from_uri
sip_from_host
sip_mailbox
sip_from_user_stripped
sofia_profile_name
sip_req_user
sip_req_port
sip_req_uri
sip_req_host
sip_to_user
sip_to_port
sip_to_uri
sip_to_host
sip_contact_user
sip_contact_port
sip_contact_uri
sip_contact_host
sip_call_id
sip_via_host
sip_via_port
sip_via_rport
max_forwards
switch_r_sdp
remote_media_ip
remote_media_port
endpoint_disposition

Okay, I have come up with what I believe
to be a pretty accurate list of channel variable names.  I’m putting
them here for reference, but the bulk of the information is in the pastebin:

http://pastebin.freeswitch.org/3432

Please let me know if you see any obvious
faults.  The pastebin has more info on how I filtered out what seemed
obviously not to be channel variables as well as which source files these
variables appear in.

Documentation Questions - updating wiki,channel variables

We don't really use freeswitch.info anymore as we now have
our own instance of drupal up.

As for the variables I try to keep them documented but I do seem to invent a
new magic variable about once a day so maybe an audit is in order.  I try
to make most of them in the code a #define in switch_types.h but there are
probably a few stragglers in the modules etc that could be found with a grep
for switch_channel_get_variable in the codebase and we could clean it up.

variables

Guys,

Just wondering if there are still blogs by anthm and pdt,
per the wiki main page:

http://wiki.freeswitch.org/wiki/Main_Page#Developer_Blogs

I know Trixter’s is still there, but what about Paul
and Anthony?  It’s looking for a domain of freeswitch.info which seems
uninhabited.  If there are developer blogs I’d like to get the page
updated with the correct links, and if there aren’t then I’d like
to get the links removed.

Secondly, I was curious about channel variables.  I
know there is a big list here:

http://wiki.freeswitch.org/wiki/Channel_Variables

I was curious to know if this list is up to date.  I
see that some are listed as ‘unknown’ which is okay for now –
I just want to make sure that all of the variables are on the list.  Are
all of these defined in switch_types.h?  (Just curious – if I know
where to look in the source I can compare the source code to the wiki list.)

Thanks,

MC
