SIP 199 Early Dialog Terminated vs 513 Message Too Large
SIP 199 (Early Dialog Terminated) is a 1xx Provisional response, while 513 (Message Too Large) is a 5xx Server Failure response. 199 indicates that a UAS can send this to indicate that an early dialog has been terminated. Used when forking results in multiple early dialogs. In contrast, 513 means that the server was unable to process the request since the entire SIP message (not just the body) exceeded the size limit.
Description
A UAS can send this to indicate that an early dialog has been terminated. Used when forking results in multiple early dialogs.
Quand vous le voyez
In forked call scenarios when one of the forked branches is cancelled because another branch was answered.
Comment résoudre
No action needed. This is normal behavior in forked call setups. Ensure your UA handles early dialog termination gracefully.
Description
The server was unable to process the request since the entire SIP message (not just the body) exceeded the size limit.
Quand vous le voyez
When the total SIP message (headers + body) is too large. Different from 413 which refers only to the body.
Comment résoudre
Reduce the message size by removing unnecessary headers or reducing the SDP size. Consider using UDP-compatible message sizes (< 1300 bytes).
