[SIPForum-discussion] why not ACK ???????????????????

[Amit Vijayvargiya]

Hi,


	 ack confirms that client has received a final Response(200) to an
 INVITE Request.

	becoz we can send different responses for invite like 180,183.... 

	but in non invite msg we send only one response .




Regards,
Amit
