What is this error? WARNING[23261]: res_musiconhold.c:719 monmp3thread: poll() failed: Interrupted system call: Nothing to worry, when the Musing On Hold process terminates to play the media file, this error is thrown out, just ignore it

What is this error? WARNING[3221]: func_cdr.c:352 cdr_write_callback: CDR requires a value (CDR(variable)=value): Nothing to worry, it is a small glitch in the dialplan, but avoiding it will require an extra check, slowing down the call processing, so it is avoided, preferring the warning. Just ignore it.

What is this error? ERROR[24984][C-00008457]: res_fax.c:4364 acf_faxopt_read: channel 'SIP/201-#######-0001547a' can't read FAXOPT(gateway) because it has never been written.: Nothing to worry, it is a small glitch in the dialplan, but avoiding it will require an extra check, slowing down the call processing, so it is avoided, preferring the error.

What is this error? WARNING[3221]: func_cdr.c:364 cdr_write_callback: Using the CDR function to set 'accountcode' is deprecated. Please use the CHANNEL function instead.: I am using an old syntax to preserve compatibility with older asterisk versions. Just ignore it.

What is this error? [2016-04-28 19:31:01] NOTICE[9505] manager.c: 217.28.216.250 tried to authenticate with nonexistent user 'admin'
What is this error? [2016-04-28 19:31:01] NOTICE[9505] manager.c: 217.28.216.250 failed to authenticate as 'admin': Someone really stupid is trying to connect using the manager interface (port 5038). The manager interface is often locked down by IP address so it is really unlikely to be hacked this way, however this can be just annoying. To stop it after a few attempts, you can tweak the fail2ban to capture also these attempts by adding the following row in /etc/fail2ban/filters.d/asterisk.conf: ^(%(__prefix_line)s|\[\]\s*)%(log_prefix)s <HOST> failed to authenticate as '[^']*'$ and reload fail2ban

What is this error? [2016-05-05 09:33:56] WARNING[26421][C-0000b22f]: chan_sip.c:7350 sip_write: Can't send 10 type frames with SIP write: Asterisk doesn't yet support comfort noise generation. Just ignore it.
