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.

Thanks,
