How do I know which version of SRST is running?

[Sandy Lee]

Hi,

I have a 3725 with IOS 12.3(8)T3, how do I know which SRST version is running? I know that version of IOS supports SRST 1.0, 2.0, 2.02, 2.1 and 3.0, but which one's running? Is there a command or a simple way to find out? Thanks.

The version of SRST that comes with the IOS version you are running is v3.1. So you are running SRST v3.1. There is no command to lookup on the CLI. You have to look at the feature matrix on CCO.

Try with "Show voice register global"

Why are you answering on a 18 year old post?

Because once I've faced same issue and found the post with the question but without the answer that I need that time. Maybe someone find my answer useful just like me when I needed.
