How do I tell what version of CallManager Express a customer is running

[patrick.hurley]

They have software S280IPV-12311T on their bill of materials. Do I need to have a show ? command run on the router to know what version it is? What command do I use for an older version?

I found it. Disregard. 3.2

sh telephony-service should help.
