Time Issue CME

Hi,

 

I have a CME in a 2911 router and 20 phones 9971 using SIP. My problem is that when I restart the router, the time of all my phones up to 3 hours from the real time of the CME.

The main configurations about the case are bellow:

 

show run

clock timezone SAS -3 0
clock calendar-valid
network-clock-participate wic 0
network-clock-select 1 E1 0/0/0

!

voice register global
 mode cme
 source-address 192.168.50.253 port 5060
 timeouts interdigit 5
 max-dn 223
 max-pool 58
 load 9971 sip9971.9-2-2SR1-9
 authenticate register
 timezone 17
 time-format 24
 date-format D/M/Y
 hold-alert
 dialplan-pattern 1 3044 extension-length 4
 call-forward system redirecting-expanded
 external-ring Bellcore-dr1
 no dst auto-adjust
 tftp-path flash:
 logo http://192.168.50.253/Desktops/640x480x24/List.xml
 file text
 create profile sync 0000476452108741
 user-locale US load CME-locale-en_US-English-8.8.2.5.tar
 ip qos dscp default video

 

ntp server 192.168.50.250

end

 

Does anyone have any idea what is happening with my CME?

Hi there,See this document

Hi there,

See this document:

https://supportforums.cisco.com/document/52901/how-do-ip-phones-get-date-and-time-cme

I recommend you try the SIP alternate method that allows phones to pull time directly from your ntp source.  This should allow them to stay in sync despite router reboots.

NPM

Shot in the dark, but how

Shot in the dark, but how about upgrading the phone firmware to something more modern than 9.2(2)SR1?

NPM

It is a good idea. I will try

It is a good idea. I will try on weekend and will report the results.

Fabio,Do you have the right

Fabio,

Do you have the right timezone selected? You should add the "ntp update-calendar" command and under the voice register global "ntp-server X.X.X.X mode unicast".
