    Added the 'storesipcause' option to sip.conf to allow the user to disable the
    setting of HASH(SIP_CAUSE,<chan name>) on the channel.
    
    Having chan_sip set HASH(SIP_CAUSE,<chan name>) on the channel carries a
    significant performance penalty because of the usage of the MASTER_CHANNEL()
    dialplan function.
