Hi Cameroun,

Please be more specific,

Is this a hypothetical question about security or can someone actually listen to the audio between 2 users.

Whats the DN for the 2 participants and the DN for third party?

Any further explanation would be helpful.

hi ZEKERIA,

Thank's for your help,

the situation was explained to me is that when anyone call if anyone picks up, he can listen to the conversation of people online . And even when it comes to outgoing calls through the PSTN .

And even when it comes to outgoing calls through the PSTN .

This is very, very possible when you're dealing with old-style analogue lines.  Like what Java recommended, please provide the setup.

You need to provide a proper explanation of the call flow and all elements involved in this, if you need urgent support, CSC is not the place for this, you want to reach TAC, or your support group.
