I have been able to register various 3rd party SIP phones with CM 5/6, but dont understand how I can invoke advanced features like "Meet-Me" & "Pick-UP" which
The SIP profile has fields for these, but am I right in assuming that unless a third part sip phone sends those values in the SIP header, the feature will not be usable ?
If that is the case, then why does cisco support SIP endpoints, if the only endpoints supported are Cisco Phones ????
I would use SCCP anyday !!
