HI HO!

Correct me if I'm wrong, but it seems you trying to use the AVPops to capture a time stamp of the very first INVITE of a transaction?  To get this same information, I've used the acc module.

For billing and user call logging purposes, I needed this info and have used: 
    acc_db_request("CallStart", "acc");
in openser.cfg.

This logs a record to the acc table containing the sip_callid, timestamps, and in "sip_status" is the string "CallStart".  I then had various scripts parse acc to the format I needed for the end user.

Hope this helps,
jj

But the name of the header changes for each transaction/dialog?
