Austin, That is strange, because I am using similar setup successfully. Actually I don't know if it counts the calls that are being established, I didn't care for it.
While looking through the docs: http://kamailio.org/docs/modules/3.1.x/modules_k/dialog.html#id2524304 the following note caught my eye: IMPORTANT: Users of this function should make sure that the dialog created is further processed statefully. Specifically, if a stateless response is sent out after dlg_manage() is called, the dialog cannot be handled properly. So make sure that a transaction exists or create it explicitly using the tm module. This is a shortcoming of the current implementation that may be resolved in a future version hopefully. Could it be that you are forwarding the INVITE statelessly?
