Service-Engine1/0 is up, line protocol is down

[Luke023]

Hello everyone,

Would you please help me to figure out what's the problem?

I have had one Cisco 2851 ISR for a few years, I lost the VoiceMail feature recently, I found 'Service-Engine1/0 is up, line protocol is down ', but I don't know why.

the settings about this service engine are as the following:

!

interface GigabitEthernet0/0.18
description <<<Voice Vlan - 192.168.18.0/24>>>
encapsulation dot1Q 18
ip address 192.168.18.10 255.255.255.0
!

!
interface Service-Engine1/0
ip unnumbered GigabitEthernet0/0.18
service-module ip address 192.168.18.11 255.255.255.0
service-module ip default-gateway 192.168.18.10
!

The IP address 192.168.18.11 can't be pinged successfully, however, the 192.168.18.10 can be pinged. 

So, when I sh interface Service-Engine1/0, I found 'Service-Engine1/0 is up, line protocol is down'.

I lost the VoiceMail function in my VoIP system, I cannot access the Cisco Unity Express (192.168.18.11) too.

Thank you help,

Mr. Luke

Got it. My NM-CUE has the same outlook as this (came from https://support.hpe.com/hpesc/public/docDisplay?docId=emr_na-c02853456

Maybe that hard drive is dead in the past 3 months. I appreciated.
