IP Phones in SRST mode

[RICHARD MESSINGER]

Want to check on something for a customer.

Thier single Call Manager died.

How long can the phones fallback to a SRST Router before they stop working?

I have in the back of my mind that the Call Manager needs to be backup within two weeks.

Am I remembering correctly?

Hi -

They will stay registered to the SRST router as long as needed.  It sounds like all other network services are OK so DHCP and IP address renewal won't be an issue (which might be the time limit you were thinking of).  

Regards,

Les,

Thanks for the information.
