SRST - Directory Services, ATA and conferencing

[hilferns]

When SRST is in fallback mode (implying the WAN is down), can I assume that users at the remote site will not be able to access the DC Directory on CallManager? Also will an ATA register with the local router in fallback mode?

Will conferencing work on the local router if enough DSPs have been provided?

Thanks

in SRST you will not be able to access the DC Directory because the DC Direcotry is co-located on the CM which you will not be able to reach remote site with the WAN being down.

ATA can register with the local router during fallback mode. Conferencing will also work in SRST if adequate DSP recourses are available on the gateway.
