I have a customer who is looking to deploy a CME SRST site abroad and want redundancy straight away. They will eventually be deploying a BE or CUCM in the UK and have multiple remote SRST sites abroad. Until that happens they want to know if they can use 2x CME SRST routers in some kind of redundancy scenario. Eventually when the CUCM or BE come online they will reduce that to one and re use the second SRST at another remote site. I don't think this is possible but I've never come across this before and would welcome any comments.
