[SIPForum-discussion] What all the SIP error codes can be sent before 180 ringing and after 180 ringing.

[Keyur Amin]

I dont believe there is any restrictions on error responses followed by 180. I think, you can have any 4xx, 5xx or 6xx messages except for 487.

 
Thanks,
Keyur Amin

After 180 Ringing, if the Callee rejects the call, you would see "486 Busy Here". Attached is a sample trace for it.
