S50 CNAM not showing on Yealink phones, Nextiva Trunk


I have an S50 connected to a Nextiva SIP trunk (register trunk), all works except the Caller ID Name, I do get a number but don't get the name.

I tried messing with the Caller ID features and all options and nothing seems to work. Is it something on the phones that I need to enable? Never had trouble with analog lines CNAM's only with this sip trunk...
