hello! new to working with sip/kamailio. I am currently trying to get a list of all of the header names on the invite the SBC receives. I am having trouble finding a way to do this. Does anyone know of a good solution?

I interpreted the original poster to be asking if there is a way to iterate over received headers in config script.

Hello,
you can access arbitrary headers from the SIP request Kamailio is processing e.g., with the pseudo-variable $hdr(My-header-name) in the cfg.
You can also dump the complete SIP message with the PV $mb.
Cheers,
Henning

Hello,
probably you can use {line} transformation in a while loop:
* https://www.kamailio.org/wiki/cookbooks/devel/transformations#lineat_pos
Skip first one and go until the line is only "\r\n", which marks the end of the headers.
For each line test if it starts with [a-zA-Z] and take the name with {s.select,0,:}.
The alternative is to use embedded interpreters for other scripting languages that provide more string parsing flexibility, like app_lua, app_python, ...
Cheers, Daniel
