intercom on yealink t20p

[asinshesq]

I used 3cx auto provisioning for two yealilnk t20p phones on my lan and on the web config page for each of those phones I enabled accept intercom and intercom tone. But when I dial *9xy on one of the phones where xy is the extension number of the other, it tells me 'Not Found'. (I did a google and concluded that *9xy is the right way to make an intercom call on these phones.) Any idea what I am doing wrong?

Answered my own question. Apparently the dial codes section in advanced do not work until you enter a demo license number in 3cx and activate it. Also, once you do that and get into the dial code area of 3cx, note that 'paging' is intercom

Just wanted to share that info in case someone else runs into this issue.
