[asterisk-dev] how to add parameter to curl post "single"

[Gustavo Hernández Baratta]

Hi!
I'm excited about possibilities using curl realtime configuration. 
Really provides an easy way to do complex things, that needed a lot of 
ingenious in previous version of asterisk.
About sip peers retrieved using curl, "single" post send name (sip peer 
username) and host (dynamic) as initial request. After that, update post 
send a lot of data. I want to add to single post a new element 
containing the source ip address of peer that are trying to register, 
but I can't find where to do it.
Is there anybody that can help me here?
Asterisk version is 11.10.2
Thanks a lot

Gustavo
