in my network i use elastix as my pbx server
but today i face a situation..
when an outside call rings someone ,not our user,can answer the phone
i heard that he say to caller that he is our employee.
he has a wireless connection to our network,meaning he is making his studying in our company,our student.
so how can i trace to that attack
i have viewed in call record.
but i didn't find any hints,meaning IP or MAC
so how can i find IP or mac of his computer in elastix

Hmmm... I think at a way.

Maybe use SRTP protocol and use auth md5.
But how to use the SRTP?

Change all admin password and other user passwords.

By the Wifi, use: WPA2 AES and not the WEP.

Make an access list.

i would also change your wifi SSID name and disable the broadcast of the name (SSID). just little things that help.

Another little thing might be to deny inbound udp on port 5060 on the wireless router.
