SRST does not fail over the PSTN it is a failover in case you connectivity to your call manager. The router will then act as a light version of call manager until you regain connectivity.

In a nutshell, route groups provide link redundancy, SRST provides call setup redundancy.

SRST is more for remote sites in case of a WAN outage, where the remote site could not contact the callmanager anymore.

Greetings,
To expand on what has been said so far, a Route Group is simply used to define an alternate (or redundant) path for Data Traffic. It provides no extra management of that traffic.
SRST is used to define how a Site can continue to operate when it is unable to reach its Call Manager(s). It is a "back-up" operation method.
These are completely separate items.
Cheers..............pk.
