Had a few calls from customers on SIP phones. Obviously, if you are using the J100 series on IP Office R11, you are going to have to implement SIP phones. J100 ONLY run SIP, when connected to IP Office R11. HOWEVER, they do work on R10.1, but ONLY as h323 phones. So, why would you downgrade all those phones just to run them on 10.1, when 10.1 will be going EOS with the next major release? Just upgrade the damn IPO.
So, to get the J series working, we need some settings within IPO set, and then the IPO will autogenerate the 46xxsettings.txt file.
