-implementors] call progress response 180 or 183 We ran into the issue a few times. We sent out "invite" message to a PSTN number. However, we didn't receive 180 or 183, but 200 ok. We know the media gateway would like to start the media immediately for transmitting call progress tone

We ran into the issue a few times. We sent out "invite" message to a PSTN number. However, we didn't receive 180 or 183, but 200 ok. We know the media gateway would like to start the media immediately for transmitting call progress tone. Is it a valid call sequence? Thanks, Jing
