If you only need to send 2 streams to each codec then you can use the “2 x Stereo Peer-to-Peer” program type and make use of the failover feature of the Distribution codecs.
To do this on the dialing codec you would create a “2 x Stereo Peer-to-Peer” program with the following settings:
1. Each audio stream would have a normal connection which specifies the IP address of the dedicated internet connection.
2. For each audio stream you would then create a “backup” connection which specifies the wireless broadband IP address
The way that the failover works would mean that the codec would automatically switch between each connection on failure, e.g. if the primary connection was lost the codec would automatically switch to the backup wireless connection. The Distribution codec is also capable of performing automatic failback (enabled by default) when the codec determines that the primary connection (the dedicated internet connection) has returned and is stable, i.e. as soon as the dedicated internet connection is up and running again the codec will flip back to using this link rather than the wireless link.
