[SIPForum-discussion] Is (200)Ok without Ringing (180, 183) a right approach?

[Sachin Parnami]

Hi *,

Is it a right approach to send Ok (200) without Ringing(180) or Session in
Progress (183)? as these are provisional responses.

UE1                                             UE2
 |              INVITE                            |
 |-------------------------------------------------->|
 |              TRYING (100)                  |
 |<------------------------------------------------- |
 |                     OK (200)                  |
 |<--------------------------------------------------|

Does it abides standards of RFC 3261?
