Three CMs or Two CMs and One SRST Reference

[ryandowdy]

Noticing documentation on CUCM and phone registration stating that a phone can receive "either up to three CUCM servers or two CUCM and one SRST reference." (emphasis mine).  Does this mean it is one OR the other; you can either have three CMs in your CM Group or you can have two CMs in a group and one SRST reference?  We've normally configured three CMs in a CM Group AND an SRST reference.  Suppose I could view a cnf file and look at it myself, but thought it would be good to ask the question here for future reference.  

Thanks,

Ryan

That's 3 CUCM servers in the CUCM group + SRST reference.
