[asterisk-users] Get sip response code

[Ken Williams]

It's funny Robert would come looking for this tonight, as I've been spending a fair amount of time trying to track this down today.  I then went to the source and found what Andreas had found below.
 
However, I'm not a real programmer, but just a hack of a hack....I tried to make my own variable but failed because I don't really know what the hell I'm doing! :D
 
Here's one form of what I tried, though I did try lots of different ways, but wasn't able to get it to compile without errors.  At best I got the server to do nothing, at worse I crashed the server when trying to use it:
 
pbx_builtin_setvar_helper(owner, "SIPRESPONSE", resp)
 
I tried this on lines 12375 & 12546 in version 1.4.4 chan_sip.c.
 
If someone who knows what the hell they are doing could tell me the correct variable for owner and if a simple (char)resp will function as it appears it wants a character not an integer, I would be ever so grateful.
 
Thanks,
Ken

vim chan_sip.c

(Hint: there are a few references, they start around line 10.000)

In app_dial.c all it does is:

                        pbx_builtin_setvar_helper(chan, "DIALSTATUS", status);

It shouldn't be too hard to add another variable for SIPDIALSTATUS or
whatever name you fancy.

That seems like a bug you should address with the vendor.
