I have tried 12.2(2)XT Enterprise plus/H323 MCM. I works fine. Just check your flash and DRAM for the recommended size.

Good Luck.

Re: Installing SRST!

Not every image supports SRST or ITS (look at the Cisco information sheets).

Attention SRST will allways run if you have the ip-phones in the same subnet and the SRST-Router is the default-gateway for the phones.

Nice day to you.

Re: Installing SRST!

IP Phones are in the same subnet, but not int the same subnet with the G/W.


do I need to get some kind of activation code to be able to activate SRST or is it just a piece of paper with a license?

Re: Installing SRST!

The phone must be on the same subnet as the gateway (i.e. the SRST device must be the phones' default router). What type of gateway are you using? A router with a spare ethernet port would do the trick. Even if you don't want to use the SRST device as your default gateway, you could use HSRP with SRST.

You need to purchase a license from your reseller to use this feature.
