for two days, I have had this problem regularly, I have to restart the phones several times and it works again…
There on the top screen, there are phones connected but all the extensions are marked unavailable (except the local extension)
Thank you for your reply!
Concerning TR-069, I think you asked the right question, the disconnections take place every 24 hours (86400 sec.), you think that if I change the time delay in the UCM only it will work, I can’t find the parameter in the station configuration in GDMS, it would be necessary to add P values?
For remote phones: there are 3 x DP752 (188.8.131.52) 3 x GRP2616 (184.108.40.206), on site a GRP2616 (220.127.116.11), the UCM6301 is version 18.104.22.168, in fact 1 GRP and one DP per site, there are currently 3 remote sites, the main company site has an internet connection dedicated to telecoms. Each time, all remote phones are desynchronized from UCM, but not from GDM, and all remote phones at the same time. I don’t receive any notifications from UCM or GDMS.
They currently have UCM RemoteConnect - Plus (expires 07/21/2024).
I have several sites with this kind of configuration, this is the only one with which I know this problem, they are all UCM with 22.214.171.124, and always with GRP 126.96.36.199 ,and TR-69 86400 sec.
SIP keep Alive is configured from the beginning, what concerns me is that all remote phones (which are not in the same location) are marked Unavailable simultaneously and only on the UCM, which is accessible without problem, I do not I didn’t change anything in the configuration and everything is now stable again.
The DP752 resets to Idle as soon as sync is forced, not the GRP2616, I have to factory reset them, a simple reset does not work.
