Hi srinivas,

for the first issue, you have to put your voice traffic in priority queue. You could use something like this:

class-map match-any VOIP

match ip dscp 40 (or 46, or what you want)

match ip address (voip traffic from a specific subnet, or host)

!

policy-map PRIMUS

class VOIP

priority

police 1000000 conform-action transmit exceed-action drop

class DATA

bandwith remaining percent 90

!

interface X

description ** PRIMUS **

service-policy output PRIMUS

!

Then, for ISP failover, and possibly loadbalancing (but not if you have a full BGP table, of course), please check:
