We have issue for transfer function in version 7.7.4 with User-Agent setup in VG.ini. Right after 202 Accepted arrived, BYE send out immediately. It drop the call before call been transfer to other number. It did not happen in version 7.7.3. For Version 7.7.3, if 202 Accepted received and NOTIFY never send back, VG will wait for 30 second to send out BYE request. If NOTIFY did come back, then BYE request send out.
