Hello everyone, this is my first post on your forum, so hope I'm writing in the right place.
I have very strange problem, some of my extensions couldn't receive calls from other extensions, when I'll restart devices, they're working for some time and then again, it's impossible to call them. First I was thinking that this problem got only one person and thought that it was caused by phone, but after replacing phone and the issue didn't solved, I started to troubleshoot and find out, that the same problem have got couple other users too (6 extensions from 62). The symptoms are the following, when someone from inside our office (all extensions are located in the same office) wants to call to his/her colleague, he dials internal (extension) number, he hears the ordinal dial tone (as if it was actually ringing) but on the other side, the destination phone doesn't care about this and is not ringing. When I try to call to that extension while running CLI, I'm getting the same error for all problematic extensions:
WARNING[8793][C-00001912]: app_dial.c:2437 dial_exec_full: Unable to create channel of type 'SIP' (cause 20 - Subscriber absent)
OK, here is my configuration details ( I have everything configured through the web form, e.g. didn't touch anything from the terminal):
OS version: SHMZ release 6.5 (Final)
Asterisk version: 11.20.0
FreePBX version: 12.0.76.2
Here is the result of the command - show sip peers:
