i have an E2O cisco tandberge that i want to register on CUCM 8.0.3 as an advanced third party sip device but as i have seen in several threads, this can be only registered as a native device from cucm 8.5. for me to be able to register it on CUCM 8.0.3, i have to downgrade it from version 4.0.2 to 2.2.
i have tried several steps but i just cannot get it to downgrade or register. i tried downgrading using Winscp, browsing to the phone IP. but it just does not get through. any ideas are hignly appreciated. for info, i activated https,htttp, telnet and ssh on the phone, created a separate sip profile on the CUCM security profile with the digest credential field marked. i get a correct IP in the voice vlan but i cannot register the phone.
I dont think it is possible, unless the endpoint is registered to CUCM. By the way, where this information comes from i.e. for me to be able to register it on CUCM 8.0.3, i have to downgrade it from version 4.0.2 to 2.2. ? Any Cisco Document says that ?
