Re: [Sip-implementors] Differences between outbound proxy and proxy

hi, Outbound Proxy: A proxy that receives requests from a client, even though it may not be the server resolved by the Request-URI. Typically, a UA is manually configured with an outbound proxy, or can learn about one through auto-configuration protocols. SIP proxy servers face the public Inter

Hi, RFC2617 defines the following rule to extract header values for calculating response: === The notation unq(X) means the value of the quoted-string X without the surrounding quotes. === and later e.g.: === request-digest = <"> < KD ( H(A1), unq(nonce-value)
