[OpenSIPS-Users] b2b refer scenario

[Anton Zagorskiy]

Hi.

Inspecting b2b_entities/dlg.c I've found that b2b_new_dlg() rejects all
non-INVITE requests.

Line 861:
if(msg->first_line.u.request.method_value != METHOD_INVITE)
{
	LM_ERR("Called b2b_init on a Cancel message\n");
      return 0;
}


So, how to use B2B REFER scenario from b2b tutorail? In this case
method_value is METHOD_REFER.
