I recently finished reinstalling my phone system after a voicemail card crash and am currently working on two issues.

Caller id not displaying on keysets.
(This previously worked..) I found an article published in forum that gave the steps to get this working and checked all steps. I have all but one of these steps completed...

Yes (Done)
AXXESS SYSTEM / PREMIUM FEATURES / ADVANCED CO INTERFACES: Must be checked yes.

No (Could not find this item in cabinets...)
AXXESS SYSTEM / CABINETS / OPTIONS CARD / DSP PROGRAMMING / CALLER ID RECEIVERS: Must be programmed and the appropriate number of DSPs installed on the OPC.

Yes (Done)
AXXESS SYSTEM / DEVICES AND FEATURE CODES / TRUNKS / TRUNK CIRCUIT / SERVICE TYPE: Caller ID option must be selected.

Yes (Done)
AXXESS SYSTEM / STATION RELATED INFORMATION / FLAGS / EXPANDED CO CALL INFORMATION ON DISPLAYS: Appropriate keysets must be included in list.

Yes (Done)
AXXESS SYSTEM / STATION RELATED INFORMATION / FLAGS / OUTSIDE PARTY CALL INFORMATION HAS PRIORITY: Appropriate keysets must be included in list.

Yes (Done)
For PRI not displaying name, Check in database programming - SYSTEM - Station Related Info - Flags. Make sure "Outside Party Information Has Priority" has all the stations listed that require Caller ID to be displayed

Both incoming lines have caller id as a service and again worked perfectly previous to the system crash.

My system cabinet consists of the following config:
01:01 Digital Keyset 16 Card
01:02 Uninstalled
01:03 Loop Start Card
01:04 Uninstalled
01:05 Uninstalled
01:06 Digital Keyset 16 Card (IP Phones)
01:07 Embedded Voicemail Card
01:08 Central Processor 0/64

Before making recommended changes the service type on the trunk had a red x on it. Now it is enabled...

(My phone lines are standard lines.. no T1, ISDN, etc...)

What am I missing here?

Additionally what is the input audio port on the voicemail card stereo or mono? I am piping music from my instore music system but the sound level is very low inside the phone system... (appears to be a connection issue....)

Have you tried this:
First Suggestion:
Try shortening the LS/GS CALLER ID RING IDLE timer. A value that seems to work in most cases is 100ms.
Try lengthening the LS/GS CALLER ID RELAY HOLD timer. A value that seems to work here is 3900ms.
Second Suggestion:
or
Try shortening the LS/GS CALLER ID RING IDLE timer. A value that seems to work in most cases is 2ms.
Try lengthening the LS/GS CALLER ID RELAY HOLD timer. A value that seems to work here is 3900ms.

NOTE: (The combination of these two timers can NOT be longer than the period between rings - typically 4 seconds or 4000 ms). Also setting the LS/GS CALLER ID RING IDLE timer lower than 100ms should not be necessary since the Cental Office sends the Caller ID information 500ms after the first ring signal stops.

Good luck

Also the audio inputs are all mono
