Will this work with grandstream ucm 6204?

It is not straight forward to configure, I did not find an option to configure SIP from the phone's web interface. You have to use the dial pad to put the user and password. I was unable to use BLF features on the phone as well. I have several Grandstream phones, different models I also run UCM6202 and a FreePBX server. Avaya phones seems to be of good quality and feature rich, but I would not recommend using them outside of Avaya environment, like FreePBX and Grandstream SIP. I bought Avaya J129 and Avaya J169 for testing and now they are back in their boxes. I do not know what to do with them.
