Outbound calls

[Emam Hossain]

Hello,
This is Emam from Alrubaishi Holding.
I having a problem with international calls, in my outbound rules I gave the 5 Ext. For international calls.
But I have noticed that, An Ext. make the international calls who were not allowed to make international calls in my outbond rules.
Except all are operational.

I am seeking suggestions on what I have to do to secure 3cx.

You have created a post to the wrong section as here is to report issues related with Security or Anti Virus Alerts.

Thanks for the response,
This is a kind of security issue.
Who had no access to international calls, but how did he make the call?

This can be a misconfiguration of your PBX. As you said it is a kind of but is not related with this forum section.

same configuration our company has been using for 3 years.
This problem we saw last month. when we disable web and app access for that ext. from that time all are good.

Hello,
Today i have faced another issue, as per my company's rules i disable some Ext. for external calls.
But after certain periods I saw that it was reverted to enable automatically.

Have you check the Audit log in the PBX?

 

[Emam Hossain]

yes, i checked it every day.
I have two outbound rules for calling outside of the organization.
For international i allowed only 5 Ext.
For the inside of ksa allowed by Groups.
