SIP 181 Call Is Being Forwarded vs 608 Rejected
SIP 181 (Call Is Being Forwarded) is a 1xx Provisional response, while 608 (Rejected) is a 6xx Global Failure response. 181 indicates that a proxy server may send this to indicate that the call is being forwarded to a different set of destinations. 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.
