from simultaneosly connecting. Well, after some discussion, i decided to implement a general solution, that shouldwork for other problems too.The idea is to execute an exeternal program every time a user
registers or unregisters, so we can setup scripts to insert data in databases, or take some actions.I made it for IAX2, but will implement that for SIP too, if needed.
An working example is:Configure iax.conf- In the section [general] add a parameterexec=/tmp/script.shThen, create the /tmp/script.sh

#Test script executed by asterisk on registering and unregistering peersecho [`date`] Received from asterisk parameters $* /tmp/output
Apply the patch, compile, copy the new channel_iax2.so, and run asterisk.Everytime asterisk receives an IAX2 message of REGISTER or a clients gets UNREGISTERED, /tmp/output receives a new line. My output now
after some tests is: [EMAIL PROTECTED]:/home/rafael/voip# cat /tmp/output [Sun Mar5 11:03:43 BRT 2006] Received from asterisk parameters register 2005 [Sun Mar5 11:03:51 BRT 2006] Received from asterisk parameters

interesting actions.The patch for this feature follows attached. By the way, would it be possible (if my code is safe and verified by someone else) to add this
to asterisk SVN? thanks [] Rafael. --- asterisk-1.2.4/channels/chan_iax2.c 2006-01-19 23:00:
