Hold failure, call is only muted. Please press hold again to unmute

When using snom D375 with firmware  snomD375-SIP 8.9.3.80 (the latest one), when trying to hold an incoming call in order to answer a new one, we obtain the following error message:

"Hold failure, call is only muted. Please press hold again to unmute".

it freezes for several seconds, which frequently causes the caller to hung up.


Unnatended transfer also don't work.Of course, the key is correctly configured.


The snoms 300 and 320 doesn't show this problem.Only the D375 ones.


I have attached sip trace and register from the phone for reference and debugging aid
