Voice Comms in Call of Duty

Do you guys know of any software that i could use for voice comms between team mates in Call of Duty. I use Ms Game Voice and its not too bad. But it has a limit of 4 players per channel. Also, sound quality is sometimes very poor.
Any ideas??

Try Ventrilo or Team Speak. Roger Wilco also used to be good, but I don't know what its like now as it's been about 4 years since I've used it.

Like Glyn says use Ventrilo or Teamspeak.

For me, Ventrilo has the upperhand

As of now the light at the end of the tunnel is switched off -untill further notice- The Management.

Downloaded ventrilo. will try it out later.

Thanks guys.

Just something I thought of reguarding Ventrilo. The free version is limited to 8 connections on the server, but only you can decide if thats enough. Secondly, it aint easy to setup the server either as it's all done through an ini file. I've set one up, so should be able to answer any queries, as long as they aren't too advanced :P
