Will most likely suit you if you are not concerned about security at all. UDP and RTP transport work great with Asterisk. Seems to be good sound quality. But TLS/SRTP? Forget it. Presumably this works with Asterisk 13.3 (or a patch - what does it mean to recompile Asterisk. Really?), but I didn't hold my breath. There are other phones that will work with TLS/SRTP almost immediately. I already googled the answers on the Asterisk forums - a Grandstream rep said TLS will give you trouble.
