60.6.1. 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.

60.6.3. 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
	To use these commands you need to have administrator or super user rights.

Type the following command to display the syntax:

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.

Meaning of the parameters:

User: Username registered in the user table (d user).
Host: IP address of the user.
Port: UDP port of the user.
REG: Registration of the user [REMOTE: Abilis is registered to a remote peer; LOCAL: a remote peer is registered to Abilis].
LIFETIME: How often (in seconds) the registration is requested.
AGE: Time (in seconds) since last valid registration.

In the previous example, Abilis is registered to the remote peer asterisk (IP address: 192.168.0.250) which needs Abilis registration each 60 seconds; Abilis registered itself 12 seconds ago.

The user zoiper (IP address: 192.168.0.24) is registered to Abilis; it registered itself 35 seconds ago.
