I'd like to do some further testing and connectivity with Asterisk and am looking into the Grandstream products for SIP hardware. I wanted to see if anyone has a preference / reviews they could offer between the Budgettone 100 or the Handytone adapter. I don't need anything super-feature-intensive but would like to have some. (lower-cost is good - thats why I'm looking at the GS) Any feedback is appreciated. - Joe
