Can Asterisk don't send 180 and 183 together when progressinband=yes??

It's not possible to get rid of the 180 Ringing as you seem to need, but it is perfectly acceptable to send 180 and then 183. The SIP implementation should just accept the audio stream from the 183 Session Progress and stop producing it's own ringing.

There's no error in sending a 183 after sending a 180.

Thanks for reporting what you suspected was a bug though. If it sounds strange on the end device, that's something for that software to fix.
