49.6. CTIIAX diagnostics and statistics

49.6.1. CTIIAX diagnostics

Use the following commands to display the diagnostics of the CTIIAX resource:

d d ctiiax

Shows diagnostic information, such as the state of the resource, the currently used channels, the remote IAX username/address/port, the calling and the called number.

d de ctiiax

Shows diagnostic information in an extended format: the same information listed for d d ctiiax command and the state of Unattended/Attended Call Transfer, the minimum/average/maximum lag value during the call and the jitter value (calculated as the variance of the lag) in least 10 seconds.

49.6.2. CTIIAX statistics

Use the following commands to display the statistics of the CTIIAX resource:

d s ctiiax

Shows statistic information, such as the number of incoming/outgoing accepted/rejected calls, the number of incoming/outgoing succesful/failed registrations, the number of incoming/outgoing succesful/failed transmission requests.

d se ctiiax

Shows statistic information in an extended format: the same information listed for d se ctiiax command are shown for each session.

49.6.3. Debug of the CTIIAX resource

Below debug commands are described. They're useful to view the authentication/registration logs and the registered IAX users table.

[Note]Note

To use these commands you need to have administrator or super user rights.

Type the following command to display the syntax:

01/06/2015 08:21:20 - [17451] Password is not valid, peer:iaxphone

This table shows data, time, identification of the event and the description of the error.

Possible errors could be:

  • Unknown user;

  • Codec not supported;

  • Retransmission out of time (happens when you are cut off).

The most common usage is:

  • debug res:ctiiax lsn:3: shows log;

  • debug res:ctiiax lsn:3 cmd:clr: clear log;

  • debug res:ctiiax lsn:3 cmd:set:err: set log mask to log only errors events;

  • debug res:ctiiax lsn:3 cmd:set:err,reg: set log mask to log only errors and registration events;

  • debug res:ctiiax lsn:3 cmd:set:full: set log mask to log any event.

The following command shows the registration table (remote peers registered with Abilis and remote peers Abilis is registered too). Registration in IAX is a way to avoid NAT troubles and maintain connectivity between IAX peers.
