Problem - Unable to Hear the Unity Voicemail Prompts

[Louis Niel Panganiban]

Hi Cisco Support Community,

I'm Louis an IT Voice Analyst. Kindly see details of my issue below:

I'm having a problem with one of our center, wherein if an outside caller want to be transfered from a phone to another internal phone the caller cannot hear any rings but take not the one at the desk hears the rings. So the caller cannot also hear the voicemail prompt and the VM became useless. I have founded a Cisco Document which is:

Hi,

I am not sure if this is related as I am a firewall expert by any means.But I see your network is full of Firewalls.

I had major problems with a CUCM cluter that was split up via JUNIPER firewalls.
I had major issues with conferencing and tranfers which was located by TAC to the JUNIPER running AVG which was spoofing skinny (SCCP) tcp port 2000.

unset alg sccp enable

Just ignore if you are not using JUNIPER
