When will TMS be able to make use of the E20's added H.323 protocol? As of right now, TMS currenly only sees the E20 as SIP only, and not the combined H.323/SIP endpoint that it is right now.
Cisco TMS 13.2.1 was actually released today, and is now available on cisco.com.
There has been plans for that for a while now and E20 H323 support should be introduced in next minor release of TMS.
This release will be out in few months.
