[c-nsp] Ios slb and voip gateway

[Carlo Maggiolini]

Hi all,
we've a 6506 that is configured to do slb for a farm of some sip servers.
My goal is to balance the traffic generated from our cisco voip gateway that
send traffic to the virtual-ip of the farm.
My problem is that the udp packets that are generated by the gateway are
always sent from the same signalling port ( 5060 ).
The slb create a "connection" between the gateway ip/port and only one real
server.
Any suggestion or idea ?
Thanks
Carlo
