Removing SDP Codec when from a specific number via HMR
                    We found a bug in our call server and while its getting fixed by the vendor were trying to come up with a work around.  Im trying to remove the PCMU VBD codec from the incoming invite so its not presented but only on calls to a certain user, but not affect the default PCMU.  I am currently trying via HMR as I thought this would be the easiest way.  I am able to easily match the user and i tested adding a new header when thats matched, but i cant get it to delete the SDP a lines.  below
