Dear All,

any help on this.....

Hi Louis

Few questions

1) Did you upload the latest firmware into the phones?or they use the default.you can check it that from the phone/hard device  what version they have...

2) The router has teh correct time?

3) do you have a ntp server configure in the router?

Note:

Every time that you do any changes into voice register global you have to issue the command create profile./Its very importand

Also check the below great doc .Will help you for sure

Hi ,

Sorry for the late response.

1.We are having the FM version kern8961.9-3-2-10. on the 8961 phones.

2.Router showing the correct time....and configured same time zone on both telephony service and voice register global.

3.I configured ntp server on the router and set reference in ntp server in the voice register global.

Tried no create profile and create profile in the voice register global.

But still the issue remains the same.

Hi,

SIP phones need an NTP reference.

It's not a problem if you don't have an external NTP server, your own router can function as one. Look at the IOS docs how to enable the NTP server functionality on your router (ntp master).

Under voice register global, you also need to set the reference: ntp-server and the IP address.

Hi,

Sorry for the late response....

I have configured ntp server (own router) and under voice register global, set the reference: ntp-server and the IP address.

But showing the wrong time yet.

Configured same time zone on both telephony service and voice register global.After change tried no create profile and create profile in the voice register global.

When I enabled the debug CCSIP messages showing the correct time.

Please guide .....

hi Nitin,

add this ...

ntp-server mode directedbroadcast

after  configuring the above reset the phones

and Also run "debug tftp events" to see what file the phone is pulling down,

then do a "more flash:" on that file to see if there is anything

suspicious.

Regards,

Karthik

show ntp status

What is the stratum of the ntp server? You may need to override the stratum.

ntp master x.x.x.x 3 ! something lower than 5

[jfernandorosa]

Hi Mike,

I changed the stratum of NTP for 4 and 3, but without successfully, the time is same in 8961.

Do you have another idea?

Thanks!

Can you post the output following?

sh run | i clock

sh run | i ntp

sh ntp status

sh ntp assoc

Also is timezone 31 the correct timezone?

Perhaps something like the following will help

voice register global
  mode cme

  ntp-server x.x.x.x mode unicast
  timezone 31
  create profile
