Greetings, im looking at putting together the following setup within our own office as per the diagram, i have an 1841 ISR terminating our leased line, an ASA 5510 For Security and a 2121 ISR running CCME for VOIP.
SIP will be the VOIP mechanism for inbound and outbound calls.
Ive labelled the diagram with a similar address block that is available for the deployment.
The reasoning behind this configuration is that i want the ISR running CCME on the inside of the firewall but still want it to have an outside IP address so that i do not have too NAT SIP traffic.
Im realy looking for clarification if this would work or could someone suggest a better method using the available equipment.
