TeamSpeak

TeamSpeak is a VoIP program used by players to communicate with each other using voice instead of typing messages back and forth. Squads usually use this for squad games and to conduct meetings that pertain to either the community or their own squad.

The client can be downloaded from the official site.

The server address is http://ts.alleg.net

Please do note that the TeamSpeak server resides outside the FreeAllegiance TOS, COC and ROC coverage and hence not enforced by @Allegs. The TS server admin's rules apply on the server and he has full discretionary power over it.
