Finally figured it out! These phone have a web interface to configure and under the server info for SIP, there is a Transport field and when I selected UDPonly, it registered! That was definitely not what it defaulted to. Thanks for everyone's help..

Hello @ingramatics ,
Thank you for reaching us.
Fortivoice 40 is an old device and it is out of order and it will be end of support on coming August. The replacement device is 20E.
Generally all Fortivoice devices are supporting standard SIP. So it suppose will work with Polycom and GrandStream as they are SIP standard as well.
You may try to configured the extension with Device Type "Generic" not "FortiFone".
Then you can manually configure the phones with Fortivoice SIP IP, Extension number, SIP password and port 5060 UDP/TCP.
Please don't hesitate to contact me if you have any further inquiries.
Best Regards,

I've never had any problems with other Polycom units but trying to get a IP550 connected and I can not get the line registered. Using the phone web interface I configure the SIP server with the IP and port 5060. Nothing configured on Outbound proxy or line identification. Ive tried both setting manufacture as Polycom and other and insert the user id and pw in the line ID section on the web. Can not get it registered. Seems like it should work..
