[cisco-voip] CME as a backup

[Matthew Saskin]

CME for SRST works pretty well, one of my clients is running it for 3 
large sites.

One caveat that I just ran into because someone misconfigured the 
gateway, leave 'srst mode auto-provision' set to 'off'.  If you turn it 
on and the gateway learns ephone-dn entries when it goes into SRST mode, 
if someone saves the config at that point the ephone-dn entries become 
permanent CME extensions, leaving some range of phone numbers 
unreachable because the gateway will try to send them to the CME phones 
that don't exist rather than the appropriate dial-peers...
