Polycom IP phone with OBI202 for landline

Disclaimer: I don't own an OBi202, so anything I post about an OBi202 might not be accurate. If anyone else wants to comment, please do.
What does your network look like? Do you have another router? Defining the OBi202 as a 2nd network can cause problems. I played with an OBi connected to a 2nd router and had to use port forwarding to get it to work as a proxy. Is your 202 defined as a router or bridge. Setting it to bridge mode might fix your problem.
I connected several SIP devices to a single SP trunk defined as a proxy on an OBi200. You just use the same credentials for all the devices. You can't use local_client option when routing inbound calls to multiple IP Phones. If you do, only the last device to register to the proxy will receive calls. You need to route the calls to the IP address and port of the phone. You also need to increase the MaxSessions parm on the SP4 Service. You should allow 2 sessions for each device connected.

Option 1 uses the 202 in router mode. Option 2 uses the 202 in bridge mode.

My setup is option 2. If i understand the instruction correctly I will need to have an ITSP Profile for each IP phone as they will be registered as the proxyserver?

No. Use the same credentials to register multiple devices to SP4.
Increase max sessions:
Voice Services -> SP4 Service -> MaxSessions: 4
Route inbound calls to the IP addresses of the phones like this:
ph,sp4(OBi202@xx.xx.xx.xx:port),sp4(OBi202@yy.yy.yy.yy:port)
You can fork the inbound call to a max of 4 devices (phone port + 3 IP phones).

according to the doc the proxy needs to be the phone's IP in mode 2: •
ITSP Profile D/SIP/ProxyServer = 192.168.1.10 (ie IP address of our SPA962 IP Phone)
