Echolink on Android

Echolink on Android works well with modest data and CPU usage.

Audio can be:

  1. wired headphones work normally, the microphone in the headphones works. You have to manually select them with the speaker icon on the top right of the app
  2. Bluetooth works poorly for me on Android and Blackberry, bad/missing RX/TX audio. Others have noted these problems too. I can tell the HSP (headset profile) is being selected.
  3. Speaker

Most people will be using “relay” connections, which precludes one-to-one connections

I wish the Echolink network stack would be upgraded to not require firewall ports to be opened, this causes some extra difficulty for users. I think most people have been using Triggered Port Forwarding to have their router send Echolink traffic to them as their IP changes on their LAN/WLAN. Or they have used Proxy Servers and now the relay method.

Skype has managed to do one-to-one connections without firewall port opening for a very long time, also using direct one-to-one and one-to-many data connections with the server used only a broker to facilitate the initial call setup.
