Selecting Enable SIP Transformations transforms SIP messages between LAN (trusted) and WAN/DMZ (untrusted). You need to check this setting when you want the firewall to do the SIP transformation. If your SIP proxy is located on the public (WAN) side of the firewall and SIP clients are on the LAN side, the SIP clients by default embed/use their private IP address in the SIP/Session Definition Protocol (SDP) messages that are sent to the SIP proxy, hence these messages are not changed and the SIP proxy does not know how to get back to the client behind the firewall. Selecting Enable SIP Transformations enables the firewall to go through each SIP message and change the private IP address and assigned port. Enable SIP Transformation also controls and opens up the RTP/RTCP ports that need to be opened for the SIP session calls to happen. NAT translates Layer 3 addresses but not the Layer 7 SIP/SDP addresses, which is why you need to select Enable SIP Transformations to transform the SIP messages.
