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
