You need to provide a lot more info and not just say the problem.

CUCM? CME? Version? Call flow?

Most usually no audio or one way audio are routing issues, start by making sure there is full routing between endpoints.

i have cucm version 10.5 ,the configuration that i used is the sip because i have ip phone 7841 sip,

session sip with server cucm is good "ring", but withou the sound for answer??

[Chris Deren]

Is this happening on all calls, or external calls only? Can you reproduce between 2 IP phones.

If external calls only are you doing NATing to your provider, is there a firewall in the media path?

[adam_obayid]

is this hapening all calls network lan

[Mohammed al Baqari]

To be clear, if you establish call between two phones in the same subnet, are you facing the problem?

[adam_obayid]

its not voice no hear any sound , but ring is good

[Jaime Valencia]

Have you already looked into routing issues??

[adam_obayid]

think you valencia i fixed the problem by "ip routing"

can you to give me example configuration voice mail please

coardialy

[Jaime Valencia]

For what system??

once again, you need to explain what you have, not just what you want

[adam_obayid]

ROUTER 2921 ios 15.5(3)M4a , cme 10.5

I WANT TO CONFIGURE AND ACTIVATE VOICE MAIL

[Jaime Valencia]

That's a whole different issue, and system, open a new thread, FYI, that's just the call control, you need to specify what you're going to be using for voicemail if you expect any assistance.

FOR EXAMPLE IF A PHONE BUSY CAN AFTER READ MESSAGE VOICE MAIL
