SCN Fallback and CCR

[sagbab]

Hi.

I'm trying to figure out the best sollution for this one customer who wants some more reciliency than what they have now. They have two offices in two different countries, where one of the offices has an IPO 7.0 with PRI and 5410 phones and CCR. The other office is connected to the same IPO and uses 5610s and has a SIP trunk that allows them to "call locally". What they see as an issue right now is that soon as the VPN goes down the phones in one office goes down. And if the main office goes down, the phones in both offices goes down.

So to "solve" this the my idea is to use one IPO at each office, both with PRIs and connected with SCN. The 5410s exchanged for 9620s,same User Rights in both IPOs. I figure that if I set it upp so that all configuration is at the main office and the 2nd office mainly acts as a fallback for the main office I will be able to use CCR for both offices and still have reciliency. So if the main office goes down all that needs to be done (hrm..) is to steer over the PRI traffic from the main office to the second office and all will be OK. Right...

I´m pretty sure Im missing something here. Anyone want tell me what it is? It would be greatly appreciated.

You are missing the point that ccr does not support a scn!
What you want cannot be done.


BAZINGA!

I'm not insane, my mother had me tested!

I don´t need CCR to work when the system is at fallback, only when both systems are up and running. And since all configuration is in the main office where also CCR is at I figured it would work. No?

When it is one ipo then yes, when you have two then no.
Each site needs it's own ccr.

So with one CCR at each site its possible to get stats even though one system is down and fallback is used?
