I have this in my dial plan:

And hook.lua has this:

dat = env:serialize()

freeswitch.consoleLog("INFO","hangup hook env:\n" .. dat .. "\n")

This dumps everything, and I don’t see the X- variables I’m looking for. I’m assuming this means I would actually need to use the event socket if I want to see them.

Subject: Re: [Freeswitch-users] Read SIP Response Headers from Dialplan or Lua

I would turn on mod_xml_cdr and look at a failed call's XML output. Look in the <variables> section and see if any of those have the data you're looking for.

Hello,

I’m wondering if it’s possible to read SIP response headers from the dial plan, or from Lua.

One of my gateways returns a generic 500 for all kinds of different error conditions, and expects me to read variables in the sip response.

e.g.

SIP/2.0 500 Service Unavailable

Via:..

From:…

Etc:

X-Custom-Var:val

The value in the custom variable might be “busy”, “bad number”, etc.

If I add something to the INVITE, I know that I can read it with channel variables “sip_h_X-Name”, but I don’t get the same thing for the response.
