I paired this up with a VM asterisk ( running in esxi ) + Polycom 331. Works flawlessly. One word of advice; I ended up setting DTFM to inband instead of RFC2833. Anything out of band was flaky or inconsistent.
The Grandstream GXW4104 is a very good solution for small offices and analog access systems. Very recommended product.
