Hello Users,
Good Morning,
What are Type of the NAT is used for OpenSER for production , OpenSER is
inside the NAT  (router/firewall )
             1)   I tested with 2 SJ phones and 2 cisco ATA phones, UAC's
are in Behind  the NAT,  UACs are in the Same N/w with one public_address,
                      SJ phone show the NAT type is Symmetric NAT in
Display...
                       this case is Working Fine,
           2) When SJ phones or HardPhones are in Different network  behind
the NAT of the OpenSER server,
                      here SJ phone shows the  Port Restricted  core  NAT
                    Here  media is not is signaling at all , in this
Case....

SIP  NAT Traversal support only Symmetric   NAT ,  ?

Then How to solve this issue ? Please  Help ?
