    However, the maximum number of vumeters that can be simultaneously displayed can be altered in the "Remote connection" tab of "General Application Values" (see section 5.1.9.1 of "AEQ ControlPHOENIX" user’s manual). The vumeters represent the transmitted audio level to the L and R channels, and the received L and R channels from the communications channel.

    "SmartRTP" can be activated in both involved audiocodecs (provided that they are AEQ Phoenix units compatible with this mode). This way, the call can be established from one end only (and thus, we only need to know the IP address and ports of one of the communication ends).

This type of connection is selected when the TALENT is used working together with an external SIP server that will provide connection with remote unit through any network, even Internet, without caring about IP addresses.

  • Page 27: Nat Traversal

    TALENT offers a total of six different operating modes when traversing devices with NAT (routers, firewalls…). Each one of those modes is suitable for a different scenario. For instance, when the units that are establishing communication are in the same local network, the internal working way will be different than when it’s done through the Internet.

    Adaptive Buffer Max/Fixed buffer length: this is the maximum size of the reception buffer. When it is defined as adaptive, TALENT will start to shorten it from this value as the network´s transmission quality allows. If it is defined as FIXED, this max value will remain, as the buffer’s size won’t be varied during the connection.
