accessible softphones for the mac?

Hello all, I was wondering if anyone knows of any accessible, preferable free, softphones for the mac? I have been trying to call a sip based number with other softphones that are nowhere near as accessible as I would like, and I was simply wondering if there are any programs out there that are indeed accessible. Thank You, Joseph King

#1 Telephone

Personally, I use Telephone http://code.google.com/p/telephone/ I's free and accessible. I use it even professionnally and I can easily put calls in hold or transfer calls. Some features are missing like a recent call view which could be really handy for me but it works pretty well. Anyway, I would be interested to hear some opinions about other SIP clients to. Best, Sof

#2 so if i have a google voice account...

so if I have a google voice account, would that count as an sip provider? or does google even do sip stuff?

#3 I personally use

App Developer

I personally use ExpressTalk. There is a free and a paid version. I use the free version and so far I have not seen any accessibility problems. In the settings dialog you need to interact with the area where all the options of a tab are located i.e. a group and that is labeled "unknown", that's all I can think of in terms of VO particularities.
