[SIPForum-discussion] Standard SIP Replies

[Adnan Aziz]

Hi Everyone,
I will be very thankful, if someone could reply the following questions
regarding SIP.


   1. Is it in SIP specification/standards to respond to the OPTIONS
   packets from REGISTERED and UNREGISTERED users?
   2. Is it in SIP specification/standards to respond to the INVITE packets
   without any prior REGISTRATION?
   3. Does the SIP standard also support the registration process using
   INVITE packets instead of REGISTER packets?


I shall be very thankful to you for your replies. Also please mention the
rfc or other authentic reference to support the answers.


Best Regards,
Adnan
