Hi,
The customers bought SX20 package with multisite option and they want to work as stand-alone device. What ports do I have to forward to SX20 codec on the firewall. Can they use SIP and H323 for calling? I tried to forward tcp/udp 5060 port to the local codec address, Is it enough for SIP, What about h323? What are the bandwith requirements. Do I need QoS? Thanks
