Hey guys/gals. Got a Cisco SPA504g sip phone registered to a 7200 v 4.53c. I can make internal calls as well as outbound calls. Works great. I don't know the pros/cons of non samsung SIP stations ie button prog, call forwarding, etc... MWI's work on the phone, but not the cfna to 5039 get a "forbidden" message. So one question is - Does CFNA and/or DND work on a SIP Station. Also, is there anyway to program buttons on the SIP Station. I can't find anything in either the Samsung manual or the Cisco manual, so here I am. Thanks for any responses.

Sip stations are generally programmed via a web interface directly onto the handset.

Ie - if you sip phone ip is 10.1.1.1 then you browse to that in your web browser and configure it.

I have used yealink phones and the park function in the phone works on a OS7200 4.4x
