How to implement auto-send Auth Proxy to BlindTransfer.
I do not know why but PBX do not send info that it is required (but is) and after invoke BlindTransfer (REFER) it's hung up.
I saw that ZOIPIER do it some how.
During session in WireShark I saw that in both cases (also ZOIPIER) there is no info from server that PROXY Auth header should be send - but ZOIPIER do it and it works - but I could not force for it - this library.
