[Freeswitch-users] How does Freeswitch CDR determine which gateway was used in failover?

Fri Apr 30 02:09:59 PDT 2010

There is/was a feature that did this: copy_xml_cdr, which sticks the b-leg CDR into the a-leg XML as a channel var. In practice I've found it sometimes just doesn't work, so don't use it if it's still there. There's also failed_xml_cdr_prefix which will write the failed b-legs into the main CDR. But I'm seeing a bug there too, where sometimes the b-leg CDR XML gets truncated. I have to do more research and I'll open a jira on it.

If you don't need the full b-leg CDR, it'll make your life a lot easier to just track the few pieces of info you need right on the a-leg by setting variables before bridging.

It's late and I can't seem to locate it right now but Mathieu Rene mentioned that there was a way to embed the b-leg cdr into the a leg cdr. Math, am I losing it? :)

Frank,

first of all, be sure you enabled writing leg B to CDR. If you don't, you won't see a gateway in there anytime soon.

In CSV CDR, you can change the template used by adding the field ${sip_gateway_name}.
In XML CDR, you get this variable automatically, of course only in the leg B file.

I am not sure if you misunderstood my question.

The XML provided by mod_xml_cdr does not tell which gateway succeeded. When I use a single gateway without failover I know the gateway specified in lastapp was used. When I use failover the last_app string contains all the gateways. I am looking for a value which tells which gateway was used.
