Grand Stream GXP1625 Date / Time settings always be resetted after reboot

bug
#1

Grand Stream GXP1625 phone’s Date / Time setting always be resetted after reboot. I set Date / Time by manually from phone led interface, without internet connection. I want to disable my phone’s NTP service. I want to set my Date/Time by manually and keep that setting after reboot.

#2

Not possible as phone do not have battery to keep time.
You need provide NTP for this, if you have PBX try check if you can start it there.

#3

Ok thanks i understand.
I have not PBX, For NTP server = my cloud SIP server address.?
Is it possible?

#4

No, It must Time server.
NAS or server ?

#5

i think it’s just server, is there any hope?

#6

Rarely SIp server is NTP server.
But you cannot use global free NTP ?

#7

Yeah.
Unbelievable, There’s on GXP phone any cmos battery can save Date value like computer or mobile,
So sad.

#8

There is no need for a battery. In order for the phone to work, it must be connected to a network and presumably, that network has some form of Internet access. A mobile phone is not a valid comparison as it is ONLY battery powered and because it is mobile, will pick up times from the cell tower/provider to which it is connected at the time.

Use the following link -
https://www.ntppool.org/zone/mn

It may help you find a NTP server.

#9

Thanks for your explanation.
In conclusion. I can’t set and save date / time without NTP server and internet connection on Grand stream GXP phones.

#10

Yes. Many devices have build in NTP, you really do not have anything in your network with NTP functions ?
NAS, PBX, Server ?

#11

My lan is connected only to SIP server directly using private address dhcp pool feeding my Voip provider.

#12

Can you ask Voip provider if they have NTP server on this separated network.

#13

I asked of them, but they told me “we don’t have NTP server this separated network”.

#14

No help then :frowning:

#15

But, thanks.

#16

How do the PCs in the network maintain their time…correctly?

#17

I think he have separate network dedicated to voip.

#18

Good point. Never crossed my mind.

#19

Doesn’t say if he is using a UCM, but if he is he can use the UCM as an NTP server.

#20

I have two separate lans. PC’s have a separate internet network.
