problem call

[alimah07]

Hi, my problem is that the users of Android and iVus outside of the company's internal network can not talk to people inside the company either internally or foreign calls. The sound of people inside the network or outgoing calls is heard, but the voices of users who are outside of the company are heard, such as a one-way call

All the firewall and netware settings have been implemented, but we did not get any results

Hello @alimah07

The first step is to run the firewall checker and making sure everything passes successfully. Please find below the list of all needed ports.

Is the issue only with extension to extension calls? Do calls with the provider work?

In each mode, calls are unilateral for users outside the network.
