By default, the OBi uses ports 16600-16998 for RTP. Hopefully, your router has an area where you can set ports to be forwarded. You would forward the range 16600-16998 to the LAN IP address of your OBi. The protocol is UDP.
Hello RonR,
I need your attention again. Can not
receive call on my phone (Sp1). Also
can not hear when i call (and get connected ) from phone (sp1) to sp2 that automatically transfers to my cell unconditionally.
This is the setting in my router
1. Set the LAN port and IP information.
Starting Port: 16600
Ending Port: 16998
Protocol: UDP
LAN IP Address: obi IP address
However, I did not put anything in the following section
2. Set the remote port and IP information. (Optional)
Starting Port:
Ending Port:

I always forward SIP and RTP ports. I give each ATA its own range of each and then explicitly forward those ranges to the appropriate device (whose IP address is fixed by static DHCP assignment). I also use a STUN server in each device (stun.ideasip.com). I have never enabled ICE or used any of the optional parameters.
Some argue that all these steps shouldn't be necessary, but in combination with Tomato firmware in the router, I never have call connection problems nor audio issues of any sort.
In case, you want to know my setting for both, ITSP Profile A & B:-
