Proxy auth with BlindTransfer #1139

Open marcinborecki opened 3 months ago

marcinborecki commented 3 months ago

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.

Could you help?
