Unity Connection , No Answer internal forwarding to Voicemail giving wrong message

[Network Admin]

Here is the scenario :-

IP Phone B - set to No Answer internal to Voice Mail.

IP Phone A calling IP Phone B .  IP phone B does not answer and call forwards to voice mail.

Then IP Phone A hears  " Enter Your Pin followed by # "  , IP phone A dials his pin and then he is getting his own greetings as if he pressed his Phone " Voice Mail " button.

Both User A and User B are added to Unity Connection Voicemail box Users.

CUCM integration with CUC is SIP.   and CUCM and UNITY vers : 10.5(2)

What Could be the issue ?

On your CUCM SIP Trunk can you try enabling the below parameter for outbound calls if not already enabled:

"Redirecting Diversion Header Delivery - Outbound"

Ideally you should also enable the inbound option as well but even if you don't do that the above should solve your problem.

Also make sure to reset the trunk after making the change. Let me know how you go.
