[英]Difference between SIP and SIPS URI?
來自RFC3261的第一個注釋:
The format for a SIPS URI is the same, except that the scheme is
"sips" instead of sip.
第二個注釋,我想是您的問題可以在第26.2.2節(SIPS URI方案)中找到,即:它表示需要保護所有躍點,最常見的是通過TLS鏈接。
When used as the Request-URI of a
request, the SIPS scheme signifies that each hop over which the
request is forwarded, until the request reaches the SIP entity
responsible for the domain portion of the Request-URI, must be
secured with TLS; once it reaches the domain in question it is
handled in accordance with local security and routing policy, quite
possibly using TLS for any last hop to a UAS. When used by the
originator of a request (as would be the case if they employed a SIPS
URI as the address-of-record of the target), SIPS dictates that the
entire request path to the target domain be so secured.
當“ Sip”出現在“ To”或“ From”標頭中時,其他規則也適用。 例如,當sips出現在To標頭中時,它表示“希望”使用安全鏈接。 在Request-URI中使用時,必須使用。
使用Sip時,您可能還需要在Contact標頭中使用Sip。 sip URI最終將在對話框中的其他請求的Request-URI中使用,因此您必須注意在Contact標頭中使用正確的sip / sip。
