Hi
As per RFC 3665 there are two call flows where in UAC sends ACK message with
proxy-authentication
Is Proxy-Authorization mandatory or optional for ack
What is the use of Proxy-Authorization header at ACK ?
As far as I understand "Proxy-Authorization" should be there for all
upcoming requests post 407/401
Please clarify
Page 30 RFC 3665
CSeq: 2 ACK
Proxy-Authorization: Digest username="alice",
realm="atlanta.example.com",
nonce="wf84f1ceczx41ae6cbe5aea9c8e88d359", opaque="",
uri="sip:b...@biloxi.example.com",
response="42ce3cef44b22f50c6a6071bc8"
