[cisco-voip] Sip design question

[Ryan Huff]

I have a pair of cubes on 4000 series ISRs. I want to do cube-ha on the ccm facing side and the itsp facing side.

1.) Am I better off just doing HSRP on both sides (which is 70% of cube-ha anyway) or is it practical to do the connected call failover portion?

2.) If I include the connected call failover,  which side would I do that one, 1 or both (ccm facing side or itsp facing side)?

Thanks,

Ryan
