How to remove Asterisk from media path

Hi All,
How do i remove asterisk from the media path between 2 end-points. I am assuming i have to change some config in the sip.conf file. Below is the area which seems related. Please let me know aht to change. I did some basic changes but did not work.

;-------------------- MEDIA HANDLING --------------
canreinvite=yes
directrtpsetup=yes
canreinvite=nonat
canreinvite=update

Thanks,
ram

canreinvite options are mutually exclusive. You probably want canreinvite=yes. If you have any network address translation between either end point and Asterisk, there is not enough information to answer properly.

You also need to make sure that the call doesn’t require any services from Asterisk that require Asterisk to see DTMF digits, e.g. t/T flags in the dial command.

Are you using parking; there are some conflicts between parking and re-invite.
