Secure Registration/Calling from DX80 over Tls via RMA

[Ovais Yousuf]

Hello All,

I have a question regarding the secure registration of a cisco endpoint e.g DX80 over MRA. The codec DX80 is registered from external network over MRA but on Non-Secure Sip Profile. But when I am trying to change the Sip profile to Secure ,it is not getting regsitered on the CUCM 11.5.

I beleive I have all correct certificates installed on Expressway C and E plus the CUCM.

Does any body has some kind of the same problem ?

Please advice for a solution :)

Thanks in advance !!

Hi Ovais,

You need to add the phone security profile name in the certificate of Expressway-C.

Please check the certificate requirement guide of expressway of your version for more details.
