We have an enterprise customer that wants to trial our SIP trunking service. They're using Cisco Call Manager v8.5 and I tried to get them to use a public IP or a private VLAN to our network, but he insists that they want to keep their CCM behind their NATing firewall.
Our softswitch has an integrated SBC, so our side is covered, but I'm afraid that they may run into some issues that are related to NAT but that we'll be held responsible.
Should I continue to push back on this customer, or let them go down this road?
If your SBC supports all the usual far-end NAT traversal measures, you should be good, particularly since this is just a single trunk. -- Alex Balashov - Principal Evariste Systems LLC 260 Peachtree Street NW Suite 2200 Atlanta, GA 30303 Tel: +1-678-954-0670 Fax: +1-404-961-1892 Web: http://www.evaristesys.com/, http://www.alexbalashov.com/
