IP Phone does not respond after a period of use


#1

Hi, I’m new using Grandstream Solutions, recently I bought and configured a IP PBX Grandstream UCM 6202 and approximately 12 IP phones GPX1625, I have an analog line connected to FXO port, I configure for a moment that only one phone can make calls outside and everything works fine, but after the phone last approximately 6 to 8 hours it stops working , does not emit tone and I have to restart the phone for working again. Can I help me please

Where is the 1625 located in relation to the UCM, same local LAN, remote?
Is the phone and UCM running the latest firmware releases?
If in the same LAN, what make model of switch are in use?
Is the using PoE or transformer?
Can you access the web GUI of the phone while in the problem condition?

Some switches reportedly have a “green” function in that they go to a power saving mode.
Sep 11, 2018 - Configuring Interface Characteristics. … This chapter defines the types of interfaces on the Catalyst 3750-X or 3560 -X switch and describes how to configure them. … Note By default, when a port i**s idle, it goes to sleep mode**.

See the above and configure the ports so that they do not sleep.
