Hi All,
I hope I can get some experts advice or answers because my brain fuses are all burned from reading and searching
1- Is it impossible to run an external SIP client behind a Restricted Cone or a Port Restricted NAT router without binding to media server, or use a proxy or use SBC (I am using STUN server and I faced no problem with full cone NATs)? if it is possible for either NAT please let me know what is the trick
I am talking about Grandstream HT-503 with 3CX Ver 3.1
I am using my own STUN server with 2 ip addresses
Both 3CX & STUN are on a public Static IP for test purposes
please let me know if this been finalized because I don't want to re invint the wheel
Thanks in advance
