[SIPForum-discussion] FAKE RBT Scenarios

[Shah Hussain Khattak]

Hello All SIP Experts, 
Can you guys please confirm me is below scenario normal:
Call Invite ---------------->
183 session in progress without SDP <----------------------------183 session in progress with SDP      <----------------------------
then
180 ringing with SDP <---------------------------------------------
i just want to know is above call flow normal? 
2nd thing, is 180 ringing with SDP creating fake RBT for calling party side? 

Regards, Shah Hussain
