Do you mean after you upgrade to firmware 25.30.0.28, there's tones before the phone auto answer, but after this, you get busy tone?
I think it's because the number you intercom is busy. Please check with other account.
Thanks.

No, I now upgraded to .30 and the same occurs.
the W52 handset phone is on the charge cradle
the handset is set to Autoanswer
I use the intercom function in Asterisk (not the built in intercom between handsets) and originate the intercom on my Yealink T22P
The W52 handset rings twice
Then the T22P phone gets a busy indicator after the two rings

In reverse, this works fine.
I use the W52 and intercom the T-22P
the T-22P beeps, then enters into speakerphone mode

Any suggestions?

Well, this may be a clue...
on my T22P phone setup page, there is "accept intercom" flag and it is set to Enabled

There is no Accept intercom setting on the W52 that I can find
