I mean there should be one more statement-

class-map type sip loadbalance match-any CIN_VOX_LB_SIP_POLICY 

match sip header Call_ID header-value sip:

and that will be called under-

policy-map multi-match GLOBAL_DMZ_POLICY

   class CIN_VOX_SIP_L4_CLASS

    loadbalance vip inservice

    loadbalance policy CIN_VOX_LB_SIP_POLICY

    loadbalance vip icmp-reply

is that missing in your config ?
