These classes were written to help systems integrators deal with the common actions of the IAX2 protocol. These were based predominantly on the protocol overview provided in the IETF draft, revision three, currently located at:

http://ietfreport.isoc.org/all-ids/draft-guy-iax-03.txt

These classes require PHP5 with mhash support.

The classes are designed to be stubs that are used by your software as necessary by assessing what functionality they provide and integrating with the files on the basis of comments and function definitions.

However, some tools have been provided in the examples/ directory, where:

./raw      Deals with raw pipes/files in libpcap format
./hex      Deals with hex dumps provided by TCPDUMP
./actions  Deals with specific IAX2 features (originate, transfer, ping)

For instance, to dump to screen details on all IAX2 communication visible on the system's network adapters, use this syntax:

cd examples/raw
tcpdump -U -w- -s0 port 4569 | ./info.php

This will then output all messages read, e.g.:

82.13.209.232   ->  213.126.5.119     *new*
213.126.5.119   ->  82.13.209.232     *auth_challenge*
82.13.209.232   ->  213.126.5.119     auth_response
213.126.5.119   ->  82.13.209.232     accept
82.13.209.232   ->  213.126.5.119     acknowledge
114.75.202.167  ->  82.13.209.232     register_attempt
82.13.209.232   ->  114.75.202.167    register_accept
194.75.202.167  ->  82.13.209.232     acknowledge
213.126.5.119   ->  82.13.209.232     voice
213.126.5.119   ->  82.13.209.232     hangup

Similarly, the ping tool can be used directly as so: cd examples/actions ./iaxping testserver

Giving output similar to the following

Ping to testserver took 3.1ms
Ping to testserver took 1.8ms
Ping to testserver took 1.6ms
Ping to testserver took 1.6ms
