[OpenSER-Users] Acc module question

[[ACTIVENDY] NOC]

Hi,

    I need to know when a channel of my media gateway is busy (included 
when the call is still ringing, etc). I have my Openser working with acc 
module storing in a mysql database. I don't use media proxy server. 

    I can see the media gateway active calls in the acc table 
calculating the INVITEs whithout BYEs call registers. But I see Openser 
doesn't insert the INVITE register still and ACK arrives. It means I 
just can view in my database the number of active calls but i cannot 
know how many call attempts there's in the media gateway. How can I do 
to Openser insert the INVITE register to my database when an INVITE 
messages arrives and don't wait for the ACK message?

Thanks in advance,

Sergi
