It may work, but officially cisco will not give support in case doesn't.
Configure username and password for authentication under a "voice register pool".
If there are problem, collect "debug ccsip messages" with "term mon".
Hi Ronen,
Logically it shd work as cisco is supporting SIP RFC's on their equipments however you may face some technical issue one hint regarding registration i can give u is increase the registration timer on Grandstream if its not gettign registree...
