How to reach SRST ip phones from Central CallManager site

I have one central site where I have Two Callmanagers in release 6. And I have several small sites where SRST will be deployed.

All phones are configured with Extension Mobility.

My problem is the following. When wan is down, I configured SRST gateway to call correctly central site Ip phones via transalation rules. But, I didn't succeded to route calls from central site to SRST sites. I try to use Forward Unregistered Internal and External with correct number via PSTN, but it's not working. I think it's because of device profile where extension mobility resides. Device profile nevers unregister. Any solution will be greateful.
