How to configure Cisco CallManager Express to allow IP phones to dial a single digit for other departments, and how to allow a receptionist to call forward directly to CUE voice mail when voice mail already has a primary and a secondary number

[TCC_2]

Core Issue

This is a Network Time Protocol (NTP) clocking issue.

Resolution

To resolve the issue, perform these steps:

1. Configure the Cisco CallManager Express as the master NTP service:
   
   This is the CallManager Express configuration:
   
   ntp clock-period 17208405
   ntp master 1 ntp server 10.66.81.91 (this is my fastethernet interface)
   
   This is the Cisco Unity Express configuration:
   
   clock timezone Australia/Sydney
   ntp server 10.66.81.91 ( this is the CME router).
   
   
2. Allow the IP phones to dial a six or a nine, and point them to other department numbers, as shown:
   
   translation-rule 20
   Rule 0 6 1000
   Rule 1 9 1003
   
   ephone-dn 2 dual-line
   number 1001
   description 1001
   name 1001
   translate called 20
   
   If you dial a six on the IP phone number 1001, it goes to 1000. If you dial a nine, it goes to 1003.
   
   When the assistant wants to dial directly to voice mail by adding an eight in front of the extention, this voice translation rule and profile strips off the eight in the re-directing number and sends the call straight to the extention voice mail box.
   
   
3. Configure a voice translation rule, as shown:
   
   voice translation-rule 1
   rule 1 /^8\(.*\)/ /\1/
   
   voice translation-profile extra_extn
   translate redirect-called 1
   
   dial-peer voice 1 voip
   translation-profile outgoing extra_extn
   preference 1
   destination-pattern 600.
   session protocol sipv2
   session target ipv4:10.66.81.94
   incoming called-number .
   dtmf-relay sip-notify
   codec g711ulaw
   no vad
   
   ephone-dn 6 dual-line
   number 81003
   call-forward all 6000
