[cisco-voip] Something SRST-like for large installations

[Lelio Fulgenzi]

If you need all phones to have dialtone then two SRST routers seems like the only alternative. 

However, do ALL phones really need to have dialtone? I mean, are there some phones you can identify as phones that don't require redundant dialtone? Some meeting rooms? Some hallways?

  Need some suggestions for something SRST-like but for large installations.

  Basically we would like to have dial-tone service in the event that the 
  CallManager cluster, for some reason, bites the dust.

  The largest SRST option seems to be 780 phones, but we often deploy 
  large subnets of 800-1000 phones.  The campus overall has 11k phones at 
  this time on one CM cluster.

  Don't yell at me for putting 11k phones on one cluster; Cisco said we 
  could do it ;-)  besides I am not at liberty to redo the whole 
  infrastructure.  I just need to make a suggestion for redundant 
  dial-tone service.

  Any thoughts?

  Bill
