[sip-comm-dev] What's the difference between the "CALL INITIALIZATION" and "CALL IN PROGRESS" states ?

Hey Emil,
            Thanks for your reply. And now i got an idea regarding this issue.

Cheers

Hey Shiva,

A call is in the CALL_INITIALIZATION state from the moment we try to

establish it until we receive a non 100 response.

A call is considered in progress once the remote party responds and you

receive the 200 OK response.

Hope this clears it.

Cheers

Emil

Hi Team,

    This shiva from TamilNadu. I hava a doubt in the states after

sending INVITE request.

Can you please tell me what's the difference between the "CALL

INITIALIZATION" and "CALL IN PROGRESS" states (Can u say with the

responses like 100 TRYING & 180 RINGING) ?

Thanks & Regards

   Shiva
