What's a reliable SIP-based GSM Gateway for a VoIP system?

I've been told that analog ones work fine. But SIP ones tend to be tricky as there is not a mature standard that they follow. As a result, the main features will work but pre-existing auxiliary features (such as call conferencing, etc) may experience issues or simply won't work, depending on both the specific GSM gateway device and the VoIP system. This is the case with the 2N product a few years ago...
So not sure what the landscape of SIP-based GSM Gateway are these days...
Whats a reliable model or brand out there, or at least a well documented one? Are there any that offer product guarantees or evaluation units? Or is plug-and-pray the only way to go?
