[OpenSIPS-Users] Manipulate SIP clients "Allow" methods when registering

[osiris123d]

I am trying to edit the Contact Header for the Register message before it is
saved.  Here is what the contact header looks like

Contact:
<sip:9000 at xxx.xxx.xxx.xxx:46356;line=bwb1k55g>;reg-id=1;q=1.0;audio;mobility="fixed";duplex="full";description="snom720";actor="principal";events="dialog";methods="INVITE,ACK,CANCEL,BYE,REFER,OPTIONS,NOTIFY,SUBSCRIBE,PRACK,*MESSAGE*,INFO".

Any idea on how to use the subst() function in order to remove the MESSAGE
(and the comma too) part from the contact header??
