[Ekiga-list] pc-to-phone recommandations?

[jdh13 <jdh13 free fr>]

hello all,
i'm using ekiga on my laptop (opensolaris) and i want to buy units to do 
cals to people not having a computer. Does anybody have recommandations? 
or user's experience? I'm wondering if this service is well suited (i 
know skype's users having some troubles)

Thanks in advance,

gerard
