The latest issue with staions on the MP 118 is 3 way calling. My gut tells me it is a station profile issue but our vendor set the stations as 9640 SIP. At first O thought that the system was not seeing the swictch hook flsh but the first call is put on hold and I can dial the second conferencee I just can't get the 3 way completed via hook flashes. I was womdering if anyone out there has hasd a similar issue.
