    5A stands for Aeta Audio Advanced Automatic Adjustment. This system makes it easier to set an ISDN connection, because the codec, on receiving a call, automatically adjusts itself, following the calling party algorithm and parameters.

  • Page 18: Pots Interface

    It must be noted that, thanks to the interoperation protocol, J52 codecs, when setting up a link, can negotiate automatically and agree on a configuration that is compatible with the capability of both units (regarding bit rate, channel mode, etc.). In this way, when the units differ in their capability (or make), the resulting configuration may be different from expected beforehand, but in most cases the link will work and audio will be transmitted.

    What happens then on the network: the Scoopy+ sends the request  (INVITE in SIP protocol) to a proxy server (often the same device is also the registrar). To make things simple, this proxy then relays and routes the request  to its destination. Resolving the SIP URI to a physical network and address uses mechanisms similar to those used for resolving URLs.

    8.3. Some methods to deal with NAT routers and firewalls Problems arise when the desired connection has to go through a NAT router, and/or a firewall, that blocks a direct IP communication. This is a very common issue, especially if one needs to set up a transfer via the Internet. It is impossible here to describe in details the possible ways to deal with this problem, but the following just shortly discusses some typical solutions.
