Hi Everyone,<div><br></div><div>1- Are the Siren7 and Siren14 the G.722 HD voice codecs?</div><div>2- Are these codecs only for Polycom units or are they universal across all other SIP phones that advertise the HD voice codec like Aastra?</div>
<div>3- What is the main difference between the two and is it advisable to run these over the INTERnet (not INTRAnet)?</div><div><br></div><div>Thanks</div>
