Re: VCSE Starterpack with only public IP in DMZ without NAT
VCS specification for SIP call as below:
- Call between SIP UA and one or both of SIP UA’s sip contact address differs from source IP address (For example, one of SIP UA is behind firewall)
VCS Expressway will treat this call as "traversal" call. This will consume traversal call license and media will routed via VCS Expressway (excluding ICE call).
- Call between SIP UA and both SIP UA’s have same sip contact address and source IP address (For example, both SIP UAs are with public IP address)
VCS Expressway will treat this call as "non-traversal" call. This will consume non-traversal call license (or traversal call license if non-traversal call license is not available & VCS run with X7.0 or newer version) and media will directly communicate between two SIP UAs (not routed via VCS Expressway).
So as Martin mention above, if your customer modify the firewall and let LAN network to NAT before accessing external network including DMZ, then call will be traversal call as SIP UA from LAN will have sip contact address differs from source IP address
