Markster understood the issue and I didn't really have the time to follow it
up.  It does need fixing though, as it is a major drawback in the current
architecture.

switch and another box running SER with grandstream phones on it So if there
is a call from the pstn it goes from the Nortel to the asterisk and then to
the SER box and finally to the phones.if the phone is busy or the number is
invalid the * box will first send an ALERT message to the Nortel and say the
call is going on and the phone is ringing (which is not the case )and after
it will send a RELEASE  message saying that the line is busy or the # is
invalid .is there any way * can send a progress message instead of the
alerting message until it gets the correct message from SER?

Call Proceeding can be sent only by transit network, not by the local switch
or pbx. AFAIK, * behavior for this scenario is like as local switch.
Certainly, this is not a normal behavior.
