Archived:KErrSIPForbidden SIP error on Symbian
SIP error: KErrSIPForbidden
const TInt KErrSIPForbidden = -17713 ,
Authentication with a server failed.
This error is due to Sec-agree (RFC 3329).
If you set "Use security" to "yes", it means that the registrar must support sec-agree.
This means that the S60 SIP stack will send Security-Client-header in REGISTER and will require that the registrar sends the 200 OK in the Security-Server-header for REGISTER.
If the registrar does not support sec-agree, set "Use security" to "no".
In this case the KErrSIPForbidden is returned by the SIP stack.
