When I use dlg_refer I get the following error:

Subject: How does dlg_bridge work?

I have a TEXT call from cust1@somedomain to Kamailio. I have an agent who is logged in, but is not in any call yet.

I want now refer cust1@somedomain to talk to agent directly. How do I do that?

I tried - dlg_bridge("$dlg(from_contact)", "$var(agentSipAddress)","");

I get an “audio call” from “Kamailio” to customer, but nothing happens on the agent side.

I tried “dlg_refer” as well but nothing happens at all.

Should I handcraft “Refer” message using uac module and send to “customer” instead?

Please suggest.

Thanks
