SRST long timeout for registation


I've set up an SRST environment with a 1751 as SRST router. My problem is about the time I had to wait before the IP Phones registering on the router. I've to wait 60 seconds at worst before the phones are operational again. On the call-manger-fallback configuration I've found the "keepalive <sec> " command but it affects only the time I had to wait before the registartion of the phones, when the CCM comes up after a failure.

Do you know if there is a way to change the the timeout before the SRST became fully functioning ?

Thanks in advance.
