SRST 4.0 or 4.1 for 3725 and 3745

Unanswered Question

Hi Guys,

We are running 3725 and 3745 with Version 12.3(8)T8 and SRST version 3.1

We would like to take advantage of some of the 4.0/4.1 SRST funtionality. I do not seem to be able to find a version of IOS for these routers with this version of SRST. Could you please help?

We are running CCM 4.2.1sr1b

Many thanks
