Folks,
It is not really ser-specific problem, but I think that it is a good
place to ask. We are having problems with getting BT/HT working with our
system - phones with firmware versions 1.0.4.26 and 1.0.4.17 don't send
ACK for final 200 OK if the in-band alerting (183 session progress) is
enabled in the remote UA. Can somebody confirm this problem? And it
seems that version 1.0.3.81 is OK, but unfortunately there is no way to
perform firmware downgrade.
Nailed it down - the damn thing doesn't like when To tag in provisional
responses differ from one in final one.
