NAT'ed IP AddressesIf you are using a NAT'ed IP address, please contact Adversus. The STUN protocol will be activated in your account, which in most cases can eliminate no sound or slow connection between our PBX and your device.In principle, we do not recommend, as a starting point, the use of a NAT'ed IP address. Please contact your Internet service provider to obtain a public IP address.
