I want to implement the Conference model with OpenSIPS server(like proxy).
So I sent REFER method using SIP Client to OpenSIPS server and I received "405 Method Not Allowed"
OpenSIPS does not support REFER method?
I have to invite someone wiht REFER message in our system.
Is there any way to implement the Conference system with OpenSIPS?

Thank you.
