Peter,
I personally don't recall seeing a posted H.323 image for a 7936. It currently has a SCCP and SIP image. Since it's a polycom rebrand maybe it can take a standard H323 image from Polycom but that's just speculation on my part. What are you trying to do with it that requires H.323? Maybe we can assist with your end result. Of course you can add a H323 gateway to facilitate phone calls to the 7936 thru CCM. Also CCM allows for H323 phone endpoints to be added as well. The 7936 running SCCP for 4.x or SIP/SCCP for 5.x will natively grant you more features with the phone in CCM. At this point Cisco has next to no support for H.323 firmwares anymore for their IP Phones.
Please rate any helpful posts
Thanks
