Hi! I am new to asterisk and i don’t know how to resolve following issue:
I have installed asterisk (version: 1.8.32.1, running on CentOS 6.6) + mysql and connected 5 test phones (D-link dph-150s with lates firmware).
Everything is fine for about 10 minutes - i can call / transfer / pickup and etc. but after +/- 10 minutes all phones become unavailable and i can see following error in asterisk console:
record in db looks like:
