External Calls to Voicemail not recording

When an internal call goes to voicemail, it is recorded and shows up on the phone and in the recordings panel; however external calls that leave voicemail are not saved and no notification is listed under the panel or on the phone. FreePBX setup info below:

PBXinF Version = 1.7.5.5
FreePBX Version = 2.9.0.7
Asterisk Version = 1.6.2.21
Asterisk Source = 1.6.2.21
Dahdi Source = 2.5.0.2+2.5.0.2
Libpri Source = 1.4.12
Addons Source = 1.6.2.3
OS = CentOS release 5.7 Final
Kernel = 2.6.18-194.17.4.e15 32 Bit

I am a novice user, so if you need logs, I will need you to tell me the commands to get said logs on SSH.

Thanks,
