Hi

I have come across this challenge:

Initial invite (no to_tag) has is authenticated and has credentials. So
a lookup for the username is made to determine if the customer needs
backhauling, thus rtpengine needs to be engaged.

On a subsequent invite (re-invite to change codec or to refresh
session timer) there is a to_tag so it is being routed without sending
a challenge and has no auth username.

I don't use dialog on the registrar. This is another transaction. So I
don't know, if I need to engage rtpengine on that DSP or not.

What is the best way to find out, if rtpengine is already handling that
callid?

if(rtpengine_query_v("j", "$var(dummy)")) {
        rtpengine_manage();
}

basically works, but generates a couple of ugly error messages in the
log as rtpengine_query_v does not find the call.

Is there a nicer way?
