| I have set up several CDP networks between BCMs and also BCMs-to-MICS via gateways.
In each instance, our network/sales engineer had the system setup preconfigured with public IPs and I configured the firewalls on each router for security.
With the number of systems to network, I would suggest MCDN/Q Sig keycodes for an efficient call flow for your intersystem transfers, etc.
I would also suggest five digit DNs with two digit destination digits at your gateway programming step.
CDP, as you know, takes the first digit(s) of the remote DN as the destination code for your VoIP Trunking and requires that each system DN range be unique from the other systems on the network.
Even though SIP is newer and more scalable, I have always used H.323 as the routing protocol because of it's simplicity for this situation.
In each systems Private network menu, your network ID is what the remote systems look for to identify it on the network, these digits must match what is setup as destination digits on the remote system. The network type should be CSE. There is no location code, that is only used for UDP.
You need to build destination codes for each remote site (example 22A, 23A, 24A, etc)and those destination codes pointing to either route O or BlocA, depending on your system. Your VoIP trunks need to be assigned to this route. |
