[SIPForum-discussion] no 180 and 183 message

[Mike Jiang]

I think it's acceptable. Not an error as I knew. 

Here is a sample case-when you called a 1-800 number, you immediately got a
voice msg played. In that case, you received a 100 trying and then a 200 OK
msg. No ringing at all.

 

Regards,

 

Mike J.

I saw a situation:

UA1 makes a call to a PSTN number, but the proxy just send back 100 and then
follows 200 message.  I though the proxy should send back 180 or 183 before
200 response.

 

Does the proxy do anything wrong?

Jing
