Raidcall and chat options

So there are a few obvious clients people use, mumble; vent, Skype, but has anyone used raidcall recently?
Only reason I ask this is because we had decent success utilizing raidcall in HoN, Im not that big a fan of ventrillo, indifferent about mumble, and hate skype (especially when it didn't work in Afghanistan).
Raidcall was having quite a few issues awhile back but if anyone has used it successfully in recent months let me know, so ill have a bit more of a definitive reason to utilize it.

I used Raidcall with some friends, it's really good, I honestly like it.

Single thing I dislike is that in-game overlay they have that buzzes me, but it just pops up if you accidentally press the shortcut which is shift + tab as Steam, but i you change it, it should be fine.

Ok cool, thanks for the info I'm gonna go through the paces with it in Dota, and hopefully there won't be many issues

I might like Teamspeak the best. It seems easier to use and the voice quality better than Ventrilo, as well as being able to add images to channels / profiles. You can use push to talk or voice activation.

We have Ventrilo and Teamspeak servers if you want to try any out. Dunno where you're located but the Vent server is in NA and the TS server in EU.

Sorry I didn't reply to this earlier, thank you for the info I'm going to have to look into those servers.
