CME to SRST upgrade question

I have a site that is configured for CME. We are linking this site with a parent site that will have a UCM 7.x/8.x in the near future. I haven't seen any definitive answer on if there is a CME to SRST license upgrade. It looks as though it is the same IOS that runs in both cases.

Is this merely a configuration change?

Obviosly the phones came with CME licensing, which will have to have DLU's purchased on the new CM.

Thanks for any help.


Re: CME to SRST upgrade question

It's the same license, just a config change. Keep in mind that you can also use CME in SRST mode. Might be an option for you. See the following link.

Hope this helps.

Re: CME to SRST upgrade question

Hi there,

Just to add a reference to the good tips from my friend Brandon (+5 points "B")

License-wise you would be good to go Here is a clip that speaks to this fact;

Q. Are there any pricing differences between Cisco Unified Communications Manager Express and Cisco Unified SRST?

A. No. The feature license pricing is the same and interchangeable between Cisco Unified Communications Manager Express and Cisco Unified SRST.

Cisco Survivable Remote Site Telephony Ordering Guide

Applications and Migration to Cisco Unified SRST

Customers who initially deploy or purchase a Cisco Unified CallManager Express (CME) solution, the CME Feature License includes a provision to use the feature license for Cisco Unified Survivable Remote Site Telephony (SRST) mode without an additional charge or re-licensing to Cisco. Customers only need to re-configure the router for Cisco Unified SRST mode.

Hope this helps!

Forgot to add this part about NOT having to purchase new DLU's

Your investment in CME phones will be protected if you upgrade to  CUCM . Have a look;

Q. I have a Cisco Unified CallManager Express (CME)  customer who wishes to upgrade to Cisco Unified CallManager 5.1. What  steps do I need to follow to ensure the licensing transfers?

A. Do the  following:

1.  Determine how many and what type of devices are on the customer's Cisco  Unified CME.

2.  Enter the quantity of each device in the "yellow" cell in the Cisco  Unified CallManager Device License Unit Calculator pasted at the end of  this document.

3.  Contact with the MAC  address of the publisher and the number of device license units  calculated in step 2. The customer does not need a node license-it comes  with the new Cisco Unified CallManager.

From this excellent licensing doc;

Cisco  Unified CallManager Licensing

Hope this  helps!


EDIT:  sorry the site won't let me attach the doc right now it is in this thread;
