Convert SRST to CME

[abddandashi]

Hello guys,

I need to convert an ISR G2 SRST to CME, should i upload a different license or it is just a matter of configuration?

With the CUE for CME or CUCM it is a license file to be uploaded, is the SRST to CME similar?

Hi,

If you purchased the SRST license, but chose to go with CME instead, the phones will still be able to register and operate with CME.   A license for SRST is valid for a customer to deploy CME, and vice versa.

Tere,

Thank you for your feedback, is it possible to have CME mode showing under the show command show voice register global?

Hi,

In fact the show voice register global output shows the if the router is on CME mode>

CONFIG [Version=8.1]

========================

  Version 8.1

  Mode is cme

  Max-pool is 10

  Max-dn is 10

Tere,

You are right about having both CME and SRST capabilities on the ISRG2, and no command for SCCP "Telephony-service" is required for conversion.

As for SIP "Voice register global" we can apply the command Mode CME or Mode SRST under voice register global and the show voice register global will show whether the mode is CME or SRST, i did not have the chance to test it if it was showing Mode CME whether it would function as an SRST or vice versa.

Thank you for your feedback, it was really helpfull.
