There are mainly three questions: regarding G.729 codec, regarding t38 fax calls and a CCA issue “Loading Voice Related Data…”
Q1. Codec G.729
Trying to activate G.729 we found two different ways but we are not sure if they are equivalent or what is the difference between them.
One way is to set the preference of g729r8 within the voice class codec.
Another way is activating g729 annexb-all via voice service voip.
The seconds way seems to activate g729 for the whole system meanwhile the first one does it for the specific voice class codec (Is this right?), but
What is the difference between g729r8 and g729 annexb-all?
Q2. Fax T.38
Activation was done like this:
UC520(config)#voice service voip
UC520(conf-voi-serv)#fax protocol t38
We have activated fax t.38 but sending out a fax, when the receiver gateway re-INVITE with T.38 cisco uc520 replied “488 Not Acceptable Media” and the fax was sent using G.711.
What else is missing?
Q3. CCA Issue
We have an issue using CCA: when we try to access any Voice related feature or AA, we get a window “Loading Voice Related Data…”, but the process never ends. We have to close the CCA session.
We tried rebooting UC520 but the behavior is the same afterward.
We attempted to reset the system to factory default but when we are not able to put offline the Service-Module Integrated-Service-Engine 0/0: when opening the session we are asked for user/password credentials and the prompt comes back shows INIT(10.1.10.1)# instead of se-10-1-10-1# . If we try to issue the offline command, we receive a message stating that module should be on-line before placing it to offline.
What would be the step to follow to have the CCA full functioning?

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
