SIP 180 Ringing vs 608 Rejected
SIP 180 (Ringing) is a 1xx Provisional response, while 608 (Rejected) is a 6xx Global Failure response. 180 indicates that the UA receiving the INVITE is trying to alert the user. This response is used to initiate local ringback tone at the caller's end. In contrast, 608 means that an intermediary machine or process rejected the call attempt. Similar to 607 but the rejection comes from the network rather than the end user.
