On the subject of using a Cisco 7960 IP phone behind NAT:
1.
Does anyone know if there are any NAT implementations that support SCCP markup, aside from Cisco's IOS / PIX routers?
2.
Does anyone know what the aspects are of SCCP that cause it to not be supported by typical NAT implementations?
3.
Does anyone know of workarounds to allow typical NAT implementations to support SCCP markup?
