No incoming call after a while

Hi all!

I am new to asterisk and FreePBX so handle me with patience pls :slight_smile: I work for a company where we have customer support and the telephone line should operate 24/7, however after a while it stops working. The caller can hear our greeting voice, but after the menu choosing there is no line. After restart asterisk its working. This happens in every 1-2 days. The telephone-line providing company says the problem is with our phone server configuration. I paste the error messages in asterisk log file maybe someone could tell me if the problem is really here:

If the configuration is correct, or cant cause this problem then what else can it be? Give me some idea pls.

Thx in advance

The caller can hear our greeting voice, but after the menu choosing there is no line. After restart asterisk its working.

Do you mean the server is not accepting any incoming calls anymore?

Do you know the age of the system & hardware?

Has the system been protected properly with a battery backup so far in its life?

Do you know what type of harddrive is in the system - Solid State, regular HDD, running off thumb drive, etc? (I have seen some various configurations in my time.)

Lastly, do you know the versions of Asterisk / FreePBX that is installed?

If there are abnormal delays, my initial guess may be hardware related. If the system is having difficulty accessing the recordings in memory, it may freeze or pause. I saw a similar situation a few years ago in a different deployment. They thought it was be good to use a thumb drive to run Asterisk but after 1 year found that the thumb drive was not a sufficient medium for running a system. It was reloaded with a regular HDD and has been running for 3+ years.
